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 L12K-Tr installed in a location protecting the LCD from direct sunlight and has 6” clearance left and right for cooling?
Y/N
2.
Are all the battery lugs tightened?
Y/N
3.
L12K-Tr should connect to grid, L12K-Tr 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: [email protected]
A.
Battery icon screen, showing detailed voltages
B.
Sol-Ark L12K-Tr 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 L12K-Tr 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
