25%, 50%, 75%, and 100% input. The NC stands for "not connected", meaning it doesn't require an input.
B – 4 stage level 2, the same as the 4 stage level 1 sensor, sensors connected to base and individual sensors to the 25%, 50%, 75%, and 100% input.
Cables: Red goes to the base input, black goes to the rest of the inputs (25%, 50%, 75%, 100%).
4.6 Batteries, Chargers, Ground, Main Switch
A - starter battery B – main battery – has the same current as the solar panel, charger. C – charger – connect to the main battery and main ground (GND). The charger has the same current as the solar panel and the main battery. D – solar charger. E – ground – connect each module that requires to be grounded to the GND. F - Manual main switch, turn the power of the SPDU-52 ON or OFF.
Note: Charger, solar panel and main battery all have the same current.
