Sol-Ark 5K Install Operational Verification Checklist Questionnaire
For installer to complete after system is operational. Purpose is to protect installer, homeowner, and inverter.
1. Is the 5K 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. 5K should be connected to Grid, 5K 63A load/Grid breakers on, batteries connected, PV input on and ON button on. With the
inverter running the Backup loads 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 5K 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 cancelling 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 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 5K is operating in 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 setup Wi-Fi plug to the customer’s internet? Y/N
12. Absolutely important for software updates. Did you help customer register system on Monitoring App? Y/N
13. Does customer have a standby generator or small portable generator? Y/N
a. Did you turn off UL1741/IEEE1547 (use General Standard) and reprogram grid freq range to 53-65Hz? Y/N
b. If small gas generator using Gen inputs, did you enable Gen charging and properly set charge current? Y/N
14. If EMP protected, did you install EMP Suppressors on essential appliance cords? Y/N
