Read this entire document before installing or using the Sol-Ark 5K-2P-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 5K-2P-N inverter is also possible, potentially rendering it inoperable.
The box should include all items shown in the component guide. If there is damage or missing parts, immediately call the phone number (USA) +1 (972) 575-8875 Ext. 2. COMPONENT GUIDE The Sol-Ark 5K-2P-N system includes the following components: Component Description...

National Electrical Code®, paragraph 110.26 and Canadian Electrical Code® CSA C22.1 are adhered to. C. The Sol-Ark 5K-2P-N is a NEMA 3R - IP65 enclosure that is rated for outdoor installation but can also be installed indoors.
2.2 Integrating Batteries Sol-Ark 5K-2P-N must be OFF while the batteries are being connected. Depending on the battery voltage, wire up the battery bank in the possible configurations shown below. C. Battery breakers must be OFF when wiring. If your battery bank does not have internal breakers, maintain the necessary safety measures when handling.
2.3 Battery Communication RJ-45 Configurations The Sol-Ark 5K-2P-N inverter achieves battery communications through a single RJ-45 port labeled “Battery CANBus”. This port combines the RS-485 and CANBus pin configurations shown below. Both “Modbus RS485” and “Battery CANBus” ports are capable of Modbus communication.
E.M.P Systems Only – Suppressor Installation If you purchased your system with Lightning / EMP Hardening, most of the protection is within the Sol-Ark. However, additional EMP suppressors are included to protect home appliances and solar panels. The Sol-Ark 5K-2P-N includes:...
AC Coupling The Sol-Ark 5K-2P-N is a system that supports the addition of AC coupled solar panels. The max solar input power can be expanded by coupling micro or string inverters into the “GEN” or “LOAD” breakers. A full AC coupled solar system is not recommended as power control and monitoring is limited.
Replicate changes for the “Normal Connect” settings. Sol-Ark will not charge the batteries using the generator unless the “Start V” or “Start %” condition is fulfilled. Only one condition (V or %) can be modified at a time depending on the control mode selected (“Use Batt V Charged” or “Use Batt % Charged”) 2.6 Grid Peak Shaving...
Compatible with Wi-Fi or Ethernet connections. 3. BMS Port (CAN/RS485) • This port is used to setup a Lithium Battery in closed-loop communication with the Sol-Ark 5K- 2P-N (consult our “Battery Communications Integration Guide” on the Sol-Ark website at www.sol-ark.com/battery-partners).
The CT sensors (or limit sensors) enhance system capabilities by enabling the use of the system work modes known as “Limited Power to Home” (Meter Zero) and “Grid Peak-Shaving”. The CTs will measure and calculate total load demand which the Sol-Ark 5K-2P-N will then use to accurately supply and offset all existing loads (Meter Zero).

AC coupled inverters need to be 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.
2.10 Emergency Stop and Rapid Shutdown The (B, B) emergency stop pins of the Sol-Ark 5K-2P-N are an ordinarily open contact that triggers rapid shutdown (RSD) when closed. RSD will cut all power including the Sol-Ark’s internal power supply and stop all AC outputs. The internal 12Vdc (-3%) power supply of the Sol- Ark (pins 15 &...
Do not ground PV+ or PV-. Verify polarity in each PV string. Backward polarity will measure 0Vdc by the Sol-Ark and will cause long term damage. PV alone turns LCD screen only. Inverter requires grid and/or batteries to operate, otherwise an “OFF” message will appear.
Parallel This tab DOES NOT have any effect on the behavior or performance of the Sol-Ark 5K-2P-N. This inverter is a single-system solution and does not support connections of multiple inverters through parallel stacking of the same model or any other Sol-Ark products.

Disable and press OK to disengage. The generator will not provide power during this test if grid power is available. The gen must be in automatic mode if applicable and must have a two-wire start (dry-contact, normally open) connected to the Sol-Ark.
To use the “GEN” terminal as an AC coupling input for micro inverters or string inverters, enable " For AC Coupled Input to Gen”. In off-grid systems, the Sol-Ark will use frequency shifting to control the AC coupled solution based on the battery SOC. The meaning of “Smart Load OFF Batt”...

V(Q): Enables the use of Volt-VAr. The Sol-Ark regulates reactive power output to the grid as a function of the voltage to support stabilization during over and under-voltage conditions. V, P & Q: Percentage of nominal grid voltage (V) to which the Sol-Ark will reduce its active power (P) or reactive power (Q). P(Q) / P(F) P(Q): Enables the use of Watt-VAr to regulate reactive power output according to programable active power parameters.
Absorption Stage When the battery has reached the absorption voltage setpoint, the Sol-Ark inverter uses constant-voltage regulation to maintain battery voltage at the absorption setpoint, preventing overheating and excessive battery gassing. The battery is allowed to come to a full state of charge at the absorption voltage setpoint.
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, securing it with screws. You will see solid red and green lights after a couple of minutes.
The system connects to grid and quickly disconnects Verify Neutral wire connection (0Vac referenced to GND) Check the programmed frequency, and verify the Sol-Ark measures 120V between L and N If the system is overloading: verify that proper phase sequence between “GRID” and “LOAD” breakers DC Overload Fault Check PV voltage.

The Batt SOC% is not reaching 100% The Sol-Ark might be in the calibration phase and estimating the battery SOC. We suggest waiting three full days to let the unit go through the 4-stage charging curve to converge to an accurate % If the suggestion above does not work, you can re-adjust the battery capacity under “Battery Setup”...
DC_VoltLow_Fault current by 20%, or Lithium BMS has shut down. If battery settings are incorrect, this can also happen. Sol-Ark is programmed to BMS Lithium Battery Mode but cannot communicate with a BMS. BMS_Communication Fault BMS_Err_Stop is enabled, but cannot communicate with a battery BMS Gen_Volt_or_Fre_Fault Generator Voltage or Frequency went outside the allowable range.
13. For Off-Grid systems: The mode “General Standard” is programmed and the V & f ranges are increased 14. When “ Grid Sell” is enabled, the Sol-Ark sells power back to the grid (negative HM measurements for L1, L2) ...
