C. Verify that every load circuit power does not surpass the above limits. Single System Install A. FOR PARTIAL BACKUP: Use a Line Side Tap as point of interconnection to integrate the utility grid to the Sol-Ark inverter through the “GRID” terminal.
Page 12 National Electrical Code®, paragraph 110.26 and Canadian Electrical Code® CSA C22.1 are adhered to. C. The Sol-Ark 30K-3P-208V is a NEMA 3R - IP65 enclosure that is rated for outdoor installation but can also be installed indoors.
Page 13: Integrating Batteries
The 30K-3P-208V reaches a max battery charge/discharge of 50A per terminal for a total max of 100A if using both sets of battery terminals. If only one set of terminals is used, the battery charge/discharge will be limited to 50A.
Page 14: Battery Communications
2.3 Battery Communications The Sol-Ark inverter can establish closed-loop battery communication through the RJ-45 port labeled “BMS1”. Configure and wire the HV batteries so that there is one battery bank with a single communication source. Closed-loop communication is established by connecting the communication cable to the “BMS1”...
Page 15: Connecting Pv Modules
AC Coupling The Sol-Ark 30K-3P-208V is a system that supports the addition of AC coupled solar panels. The max solar input power can be expanded by coupling 3Φ micro or string inverters into the “GEN” terminals. A full AC coupled solar system is not recommended as power control and monitoring is limited.

Page 17: Integrating Sensors And Accessories
If connecting more than one HV battery in parallel to the Sol-Ark inverter, divide the Gen or Grid “A” value by the # of batteries to estimate the current (A) flowing to each HV battery.
Page 18 CAN port data is in a proprietary format. Sol-Ark does not support 3 party usage currently. • The RS485/RTU port utilizes the MODBUS protocol, data is in a proprietary format. Please contact Sol-Ark to request an NDA if the MODBUS mapping is required for your application. RS485...
Page 19: Limit Sensors (Ct Sensors)
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 30K-3P-208V will then use to accurately supply and offset all existing loads (Meter Zero).
Page 20 This function REQUIRES batteries to auto detect and auto correct CT orientation. 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 previously.
Page 21: Emergency Stop And Rapid Shutdown
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 (CN2, pins 7 & 8) will disconnect any RSD transmitter that will then shut down all solar panels when the emergency stop button is pressed.
Page 22: Powering-Up And Testing The Sol-Ark
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.

Page 27 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.
Page 28: Limiter
Limiter The Sol-Ark 30K-3P-208V inverter will simultaneously utilize different available power sources to satisfy load demand in the electrical service panels (essential loads panel / main service panel). The following work modes allow the user to determine how power is generated and utilized.
Page 29 “LOAD” terminal (essential loads panel) + excess power to the “GRID” terminal (main service panel AND grid). The Sol-Ark will monitor grid sell and load consumption simultaneously (with +/ - 3% error from CT sensors). The CT sensors MUST be installed.
Page 30 “LOAD” demand and sell excess solar up to a programmable limit. “GRID” loads cannot be measured, only the total output through the “GRID” terminal.

Page 33 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.
