Sol-Ark 8K Install Operational Verification Checklist Questionnaire
For installer to complete after system is operational. Purpose is to protect installer, homeowner, and inverter.
1. Is the 8K installed in a location protected from water and has 6” clearance left and right for cooling? Y/N
2. Are all the battery lugs tightened? Y/N
3. 8K should be connected to Grid, 8K 50A load/Grid breakers on, batteries connected, PV input on and ON button on.
Leaving all 10 transfer switches on Line/Grid, test circuit only one at a time to Gen/Solar and then back to Line.
Wiring should be correct if you do all 10 to verify no breakers pop or inverter overload.
a. Did any breakers trip? Y/N
b. Did inverter overload? Y/N
c. Set all switches to Gen/Solar.
4. If you have problems, please take pictures of these and email to: sales@ Sol-Ark.com
a. Battery icon screen, showing detailed voltages (the screen shown below)
b. Sol-Ark 8K with batteries and of user wiring area
5. Load and solar test
a. Did you do this entire section with the customer to explain the home screen and the detailed voltages
screen? Y/N
b. Press the battery icon for the detailed voltages screen.
c. Is batt temp sensor working? Y/N
d. Turn on many loads for the critical circuits. Are solar panels producing enough power to match the load
(provided there is enough sun)? Y/N
e. Verify screen in limited power to loads mode (default). Are both Grid Home measurements positive? Y/N
f. 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
g. 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
h. You have verified the limit sensors are correctly installed. If MCU Software is 1664 or higher, an auto learn
function corrects any mistakes in limiter wiring. Program in the correct Grid mode the customer will use.
6. Did you program the correct Ah for battery bank and ~20% 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 8K 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
