Install Verification Checklist
For installer to complete AFTER the system is operational. The purpose is to protect the installer,
homeowner, and inverter.
1. Is the 12K installed in a location where the LCD is protected from direct sunlight and has 6" clearance left and right for cooling
(12" between parallel systems)? Y/N
2. Are all the battery lugs tightened? Y/N
3. 12K should connect to grid, 12K 63A load/Grid breakers ON, batteries connected, PV input on and ON button on. With the
inverter running the Backup load's panel and Grid-connected:
A. Did any breakers trip? Y/N
B. Did inverter overload? Y/N
4. If you have problems, please take pictures of these and email to: support@ Sol-Ark.com
A. Battery icon screen, showing detailed voltages (the screen shown below)
B. Sol-Ark 12K with batteries and of user wiring area
5. Load and solar test
A. Press the battery icon for the detailed voltages screen.
B. Is batt temp sensor working? Y/N
C. Turn on many loads for the Backup circuits. Are solar panels producing enough power to match the load (provided
there is enough sun)? Y/N
D. Program Full Grid Sell Mode. If there are enough panels and sun or light loads in the entire house, the Grid HM
measurements will be negative on both L1/L2. Are they negative (solar selling back to grid)? Y/N
E. Program limited power to home mode. The Grid HM sensors will be near zero or slightly positive. Are they both near
zero and canceling out the whole home power? Y/N
F. You have verified the limit sensors are correctly installed. An auto-learn function corrects any mistakes in CT limiter
wiring (provided you have batteries and in 120/240V). Program in the correct Grid mode the customer will use.
6. Did you program the correct Ah for the battery bank and max Amps charge/discharge? Y/N
7. Did you program the correct battery charge voltages for your battery type? Y/N
8. Turn off the AC breaker, so 12K is operating in an off-grid mode for several minutes. Are appliances still powered? Y/N
9. Turn off PV input, running only on batteries for several minutes. Are appliances still powered? Y/N
10. Turn on PV input and AC Grid inputs.
11. Did you set up the Wi-Fi plug to the customer's internet? Y/N
12. Absolutely important for software updates. Did you help the customer register system on Monitoring App? Y/N
13. Does the customer have a standby generator or a small portable Generator? Y/N
A. Did you turn off UL1741/IEEE1547 (use General Standard) and reprogram grid freq. range to 55-65Hz? Y/N
B. Did you enable Gen charging and adequately set the charge current if using a small gas generator on Gen inputs? Y/N
14. If EMP protected, did you install EMP Suppressors on essential appliance cords? Y/N
