WARNINGS Read this entire document before installing or using the Sol-Ark 5K-1P-N inverter. Failure to follow any of the instructions or warnings in this document can result in electrical shock, serious injury, or death. Damage to the inverter is also possible, potentially rendering it inoperable.
The box should include all items shown in the component guide. If there are damages or missing parts, immediately call (USA) +1 (972) 575- 8875 Ext. 2. COMPONENT GUIDE The Sol-Ark 5K-1P-N system includes the following components: Component Description Quantity...
Heat transfer is done from bottom to top at a rate of 115.2 W/hr ≥ 2 in [5 cm] ≥ 2 in The Sol-Ark 5K-1P-N is a NEMA 3R - IP65 enclosure, rated for outdoor installation but [5 cm] can also be installed indoors. PROTECT LCD screen from direct exposure to UV light.
Sol-Ark 5K-1P-L is a 48Vdc nominal system. DO NOT connect the inverter to any other battery configuration. If you use 12V batteries, you MUST NOT exceed four (4) batteries in series, as shown in Figure 5b. The inverter can work with any battery chemistry if it remains within the range of 43V to 63V.
AC Coupling The Sol-Ark 5K-1P-N is a system that supports the addition of AC coupled solar panels. The solar input power can be expanded by coupling micro or string inverters into the “GEN” or “LOAD” terminals. A full solar AC coupled systems is not recommended as power control and monitoring is limited.
1P-N. Additionally, increase the voltage range to “Grid Volt High=130V” and “Grid Volt Low=110V”. Sol-Ark will not charge the batteries using the generator unless the “Start V” or “Start %” condition is fulfilled. Only one condition (V or %) will be modifiable depending on which control mode is selected under (“Use Batt V Charged”...
GEN or GRID “A” value will ensure that small generators are not overloaded when charging the battery bank. If connecting more than one Sol-Ark in parallel, multiply the GEN or GRID Start “A” value by the # of Sol-Ark inverters to get the actual current (A) what will go into the battery bank.
The CT sensor (or limit sensor) enable the use and smooth operation of the system work modes known as “Limited Power to Home” and “Grid Peak-Shaving”. The CT will measure and calculate the demand in the Main Service Panel which the Sol-Ark 5K-1P-N will use to accurately supply and offset all home loads.

OFF during the detection test. If this test is done with connected AC-coupled systems, a factory reset of the Sol-Ark must be performed. Install the CT sensor as described in section 2.9 “Limit Sensor”. A battery connection and grid power are required before starting the automatic configuration.
Voltage of the battery must be between 43Vdc - 63Vdc. If applicable, turn “ON” internal switches of battery modules or battery pack. Measure individual voltages. C. Verify proper voltage of the battery bank at the battery terminals of the Sol-Ark. 2. Check the voltage of each PV input circuit Input voltage must not exceed 500Vdc.
TURN OFF the external battery disconnect. Wait a moment (~1 min) to ensure the inverter is completely de-energized. Make sure that the Sol-Ark is properly connected to the batteries, solar panels, grid, gen, and loads. Reverse the steps to turn ON the inverter 2.12 LED Indicators...
Load Limit Power: Sets the total AC output power from the batteries to the “LOAD” terminal of the Sol-Ark. The default value is always the maximum output of the inverter production.

Gen Force: Closes the two-wire start relay. If a generator is connected to the two-wire start relay and is under automatic mode, then it will automatically start. The generator must be in automatic mode if applicable and must have a two-wire start (dry-contact, normally open) connected to the Sol-Ark. To disable the Gen exercise, adjust the time duration to 0 min.
AC Coupling Settings - (For AC coupled input) Sol-Ark 5K-1P-N is a 120Vac system. AC coupled solutions such as micro or string inverters must be 120Vac. Sol-Ark must be programmed for nominal 240V if planning on adding 240Vac AC coupled solutions A.

In this mode, the inverter delivers power to the “LOAD” terminal (essential loads panel) + unlimited power to the “GRID” terminal (main service panel AND grid). The Sol-Ark will monitor grid sell back and load consumption simultaneously (with +/ - 3% error from CT sensor).

All time intervals are automatically enabled. Power(W): This is the maximum discharge power the Sol-Ark will draw from the battery during the time intervals. Batt: Voltage or percentage battery state-of-charge at which the system stops discharging batteries. If “ Charge” is checked, the “Batt”...
3.4 Grid Setup Grid Selection The Sol-Ark 5K-1P-N has a wide selection of (single phase) AC voltages it can operate in, including: 120V, 127V, 220V, 230V and 240V. Output power will vary depending on grid type selection: 4,800W @ 120V and 127V 8,000W @ 220V, 230, and 240V See section 1.2 “Specifications”...
When off-grid, there is no need for a transfer switch. Connect the “LOAD” output of the Sol-Ark to the whole home. Do not use “Grid Sell” mode when Off-Grid. ONLY “Limited Power to Load” (default) in systems with only 1 inverter, and “Limited Power to Home”...
Tech Support for assistance: support@sol-ark.com Parallel systems REQUIRE a joint battery bank. If you do not have a battery, keep all Sol-Ark's OUT of parallel and set every System to “Grid Sell” Mode. D. All INPUTS/OUTPUTS must be shared among ALL parallel inverters, with the exception for DC solar inputs.
Insert the ethernet cable through the plastic enclosure and connect the cable to the RJ45 port. C. Reassemble the dongle housing and plug the dongle into the Sol-Ark. Secure with screws (see figure 37). You will see solid red and green lights after a couple of minutes.

Wait a moment (5 min) for the dongle to connect. If successful, you should see a red and green light on the dongle showing a solid connection. RED LED: Connected to Sol-Ark and has power. GREEN LED: Connected to router and server.
