The solar charge controller is responsible for charging the battery and turning on/off the DC loadfrom the solar cells.

Q: What battery type is this controller supported?

...

We will be using the b02 setting for Lithium Ion 3S.

Solar Panel

We have a flexible 100 watt solar panel from AllPower.

• AUTOMATIC VOLTAGE DETECTION: detects whether your battery requires 6 or 12-volt charging and features preprogrammed 8-stages charging process
• LCD SCREEN: displays real-time charging voltage/current and battery bars; lets you know about the battery charge status with just a glance
• MULTI-PROTECTION: features reverse polarity protection, over-temperature protection, overcharge protection; also comes with spark-proof clamps
• WIDE RANGE USE: efficient use with all SLA batteries (Wet, MF, GEL, VRLA and Flooded), AGM (EFB), LiON (12V LiFePO4)
• BATTERY MAINTAINER: provides a 24/7 constant voltage charge for optimum battery maintenance

The LCD Screen provides you status of the charging directly with big and clear fonts . You can read the real-time charging current and voltage as well as diagnostic information. And its backlight feature makes it easy to read in darker places.

Inverter

Our inverter is a 3000W Motomaster modified sine wave inverter. We don't use a lot of AC and we had this laying around. This inverter in not suitable  for sensitive equipment since it is not a pure sine wave inverter. At some point, I may upgrade to a pure sine wave inverter.
