System Setup

System Wiring

The wiring diagram only shows the key components in a typical DC-coupled off-grid energy storage system for the illustrative purpose. The wiring might be different depending on the system configuration. Additional safety devices, including disconnect switches, emergency stops, and rapid shutdown devices, might be required. Wire the system in accordance with the regulations at the installation site.
The grid supplies the connected loads only. It does not charge the battery.

Unit Wiring

The wiring diagram provided in this section is tailored for a 1000W inverter model. Similar wiring rules apply to other models.

Size a Battery Bank

Battery types and capacity relate to the overall inverter performance. To size a proper battery bank, you need to identify the loads that you will be utilizing, as well as an estimate duration (hours/day) you will be using the load. The inverter is only compatible with 12V battery banks, and oversizing should be considered due to efficiency losses.

1. Determine Your Watts (Amps x Volts)
   Every electronic device will have a sticker or plate identifying the watts directly (W) or will show you the voltage value (V) as well as amperage (A) which need to be multiplied to get Watts. The formula is below:
   Watts (W) = Volts (V) x Amps (A)
   Example: Fan Watts = 120V * 0.4A = 48Watts
2. Estimate Load Run-Time in Watt-Hours (Wh)
   Estimate how many hours per day you will be using the load and multiply this by your Watts per load.
   Example: Fan Watts x 12 hours = Watt-Hour (Wh)
   48W x 12h = 576Wh
3. Determine Battery Capacity in Amp-Hour (Ah)
   Divide your Load Run Watt-Hour result by the battery voltage.
   Load Run-Time (Wh)/Battery Voltage (V) = Amp-Hour (Ah)
   Use 12V, supported voltage of the inverter as a reference.
   576Wh/12V = 48 Ah
4. Oversize the Battery
   The calculated Amp-Hour value represents the minimum size battery capacity to run your load for your intended time. Note that this assumes 100% use of a battery, which is not recommended. Assuming 50% depth of discharge, you want to multiply this value by 2 and you also want to multiply by 1.25 to account for some efficiency losses.
   Formula:
   48Ah x Oversize x Efficiency Losses = Recommended Amp-Hour
   48 x 2 x 1.25 = 115Ah
   Therefore, a 115Ah battery bank, or close, will be able to support a 12-hour run time while also prolonging battery life for the best system size possible.

Actual battery quantities vary by battery capacity and rates of discharge.

Wear Insulating Gloves

This manual utilizes the 1000W Inverter as a reference for its illustrations. The wiring techniques remain consistent across all inverter models, though there may be variations in terminal positions.

Plan a Mounting Site

Follow the guidelines below:

• Cool, dry, and well-ventilated area
  The inverter must be installed in a site where the fans are not blocked or where they are not hit directly by the sun. The site should be free of any kind of moisture with a clearance of at least 10 inches around the inverter for adequate ventilation.
• Protection against fire hazard
  The inverter should be away from any flammable material, liquids, or any other combustible material.
• Close proximity to battery bank
  Put the inverter close to batteries banks to prevent excessive voltage drop. Choose a proper sized wire going from the battery bank to the inverter.
• Limiting electromagnetic interference (EMI)
  Ensure the inverter is firmly grounded to a building or vehicle. Alternatively, it can be earth grounded. Keep the inverter away from EMI receptors such as TVs, radios, and other audio/ visual electronics to prevent damage/interference.
• Secure mounting
  The inverter should be stand-alone or mounted by using the outlying terminals with ST4 and ST6 screws on the inverter.
  

Do not over-torque or overtighten the terminals. This could potentially damage the unit.
Refer to the technical specifications for maximum wire sizes on the controller and for the maximum amperage going through wires.
Ensure the inverter is in the OFF position before connecting to anything.
Do not install the inverter in the same compartment as the battery bank because it could serve as a potential fire hazard.
Never mount the inverter vertically on a vertical surface since it would present a hazard for the fan opening, undermining cooling the inverter.

How to Properly Install Cable Clamps?
The AC Output Port with cable clamps to ensure that the wiring connections remain secure and do not come loose due to vibrations.

1. Loosen the screws on a cable clamp with a Phillips Screwdriver.
2. Lift the clamp, and run the cables through the clamp.
   (You will need 1 x 3 prong (10 AWG recommended Black, White, Green) ac cables not provided with this product. Measure the required length for your particular application. for ac output of the inverter. SJT0 and SJT,SJ0 are recommended wire)
3. Secure the clamp by fastening the screws

Do not use the bare wires if there is any visible damage.
Do not use SP-3, SPT-3 type wire
The screw torque of a cable clamp is 14.16 in.lbs (1.6 N.m). Do not over tighten the screws to prevent damage

Grounding

Grounding is highly recommended for both when using the inverter in a mobile application, such as an RV, or in a building. If available, the chassis ground lug should be connected to a ground point such as a vehicle chassis or boat grounding system. In fixed locations, connect the ground lug to earth ground. The connections to ground must be tight and against bare metal.

Model	Recommended Size
1000W Pure Sine Wave Inverter	14 AWG
2000W Pure Sine Wave Inverter	12 AWG
3000W Pure Sine Wave Inverter	10 AWG

When the GFCI fails to operate normally after grounding the inverter, please refer to "N-G Bondinq Relay" for details.

DC Wiring

The inverter is suitable for 12V battery bank systems ONLY. Not following the minimum DC requirement will cause irreversible damage to the device.
The input terminals of the inverters are embedded with large capacitors. The input circuit is completed once the terminals are connected to both positive and negative wires. This commences drawing a heavy current momentarily. As a result, there may be a sparking occurring even if the inverter is in the off position. To minimize sparking, it is recommended that you should choose an appropriate sized wire feeding into the inverters and/or install an external fuse leading into the inverter.

Be careful of the positive and negative poles. Reversing the poles might cause permanent damage to the inverter and will void the warranty.

For your safety, it is recommended that you should use a battery fuse on the positive end.

Continuous Output Power	1000W	2000W	3000W
Battery Fuse	150A	250A	400A

1. On the AC side, set the ON/OFF Switch to the OFF position.
   
2. On the DC side, remove the protection caps.
   
3. Unscrew Positive and Negative DC Input Terminals, connect a battery bank to the terminals, and tight the terminal screws. Torque: 14(± 0.5) N•m
   

AC Output Wiring

Recommended Ground-Fault Circuit Interrupter

A ground-fault circuit interrupter, or GFCI, is a device that helps protect people from electric shocks by de-energizing a circuit or portion of a circuit within an established period of time when a current to ground exceeds some predetermined value that is less than that required to operate the overcurrent device (circuit breaker or fuse) of the supply circuit. GFCIs are usually required in wet or damp locations.
While the inverter is equipped with a GFCI, an external GFCI is strongly recommended to elevate system safety.
The following table lists GFCIs that meet the specifications and will function properly when they are connected to the AC Outlets of the inverter.

Tested GFCI Models
Manufacturer	Model Number
Leviton	GFNT2
Hubbell	GFP1305
Hubbell	GF15WLA

Risk of electrical shock. Use only ground-fault circuit interrupters [receptacle(s) or circuit breaker(s)] compatible with your inverter.
GFCIs shall be installed in a recreational vehicle's wiring system to protect all branch circuits.

AC Outlets

You can plug your AC loads directly into the AC Outlets on the inverter's AC side.

High Output AC Terminals

Additionally, you have the option to establish a permanent connection from the AC output by linking it through the High Output AC Terminals to a GFCI, a load sub-panel, or supplementary AC outlets that receive power from the inverter.
From left to right, the terminal block indicates: Ground (G), Live/ Hot (L), and Neutral (N).

For details on how to connect loads and the inverter to the GFCI, read the user manual of the specific GFCI.

AC Input Wiring

(Optional)
Utilizing the built-in transfer switch, this inverter seamlessly switches to grid power, bypassing the inverter when it's available, thereby directly supplying the load with grid power.
From left to right, the terminal block indicates: Live/Hot (L), Neutral (N), and Ground (G).

Risk of electric shock! Ensure the grid or the AC generator is turned off before connecting them to the inverter.

Power On/Off

Operations on the Unit

After proper battery and AC load connections, you can operate the inverter.

1. On the AC side, rock the ON/OFF Switch to the ON position.
2. The inverter is operating normally.

When finishing using the inverter, power off the AC loads first, and then rock the ON/OFF Switch to the OFF position.

When the inverter turns on, it is normal to see the fans run for a second and hear a beep.
Avoid powering on the inverter with the load (electronic devices) already switched on. This may trigger an overload since some electronic devices have an initial high power surge to start.
When switching off the inverter, turn off the electronic devices first. Although the inverter is off, the terminal capacitors will still have a charge, so the DC and AC terminals must be disconnected if altering the circuitry.

Wired Remote Control

The Wired Remote Control gives you the opportunity to power on/off the inverter from a distance (approximately 16.4 ft / 5 m).
Note that the inverter ON/OFF switch should be in the REM position.

1. Connect the Wired Remote Control to the inverter via the Remote Control Connector.
   
2. Rock the ON/OFF Switch to the REM position, and you can power on/off the inverter via the Wired Remote Control.
   

N-G Bonding Relay

The inverter is equipped with a Neutral to Ground (N-G) bonding relay that ensures that either the neutral in or out contact of the RV is always grounded.
This helps prevent electrical shock caused by contact between the neutral contacts of the RV and external AC power sources.
By default, the Neutral to Ground bonding relay is enabled when the inverter is shipped from the factory.

• When there is AC input current, the N-G bonding relay automatically opens the neutral-to-ground connection as shown in the figure below, and the system connects to the grid ground contact.
  
• When there is no AC input current, the N-G bonding relay automatically closes and connects to the ground contact of the inverter. In this case, the inverter supplies loads with the connected battery.
  

In scenarios where the N-G bonding relay is disabled, the N-G bonding relay connects to the ground contact of the inverter only.

You have the option to manually enable or disable the N-G Bonding Relay.

The N-G bonding relay must be enabled when the battery supplies the connected loads because the GFCI will be unavailable if the N-G bonding relay is disabled.
In scenarios when N-G bonding relay is disabled, the inverter must be grounded.

Monitor the Unit

Depending on the specific application, the inverter can establish either short-range or long-range communication connections with monitoring devices. These monitoring devices facilitate real-time monitoring, programming, and complete system management, offering comprehensive control and enhanced flexibility.

The version of the DC Home app might have been updated. Illustrations in the user manual are for reference only. Follow the instructions based on the current app version.
Make sure that the inverter is properly installed and powered on before it is paired with the DC Home app.
To ensure optimal system performance, keep the phone within 10 feet (3 m) of the inverter.

Download the DC Home app. Login to the app with your account.

Short-Range Monitoring via DC Home App

If only short-range monitoring is required, connect the inverter to the DC Home app directly through the Bluetooth of your phone.

Wireless Long-Range Monitoring

If long-range communication and programming are required, connect the inverter to Renogy ONE (sold separately) through Bluetooth, and the Renogy ONE to the DC Home app through Wi-Fi.

Pure Sine Wave

The inverter outputs a pure sine wave similar to the waveform of the grid power. In a pure sine wave, the voltage rises and falls in a smooth fashion with very low harmonic distortion and cleaner utility-like power.
This technology allows the inverter to supply electronic devices that require a high quality waveform with little harmonic distortion. In addition, the technology enables the inverter to be more efficient than traditional ones, allowing you to use less energy to supply more devices. The inverter can provide sufficient, stable power for tools, fans, lights, computers, and other electronics without any interference.
