Lead Acid Battery Tab Wiring
This is the last of our wiring for SolarMAX2.
Step 1) CHECK YOUR WIRING for BATIN on the Solar Controller Board (Part D). Specifically, steps W1, W2
and W7 in the wiring chart above! CHECK IT AGAIN. If you get this wrong, you will destroy your
controller.
Step 2) Take the Red Cold Press Crimp spade connector and place the stripped wire from the INA1+ Screw
down connector on the INA3221 ADC (Part C) into the spade connector and crimp the connector to hold them
in place (and make connection with the spade).
