Solar Charge Controller

Model: ALLPOWERS 20A Solar Charge Controller Solar Panel Battery Intelligent Regulator-Blue

The solar charge controller is responsible for charging the battery from the solar cells.

Q: What battery type is this controller supported?

A: (1)B-01=LEAD-ACID, 12V; B-02=LITHIUM ION 3s, 3*3.7V=11.1V; B03=LIFePO4 4s, 4*3.2V=12.8V. (B01 is the default type, If you would like to to switch to another 2 types, please select it manually.)

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

Solar Panel

We have a flexible 100 watt solar panel from AllPower.

Battery

We will be using a DIY 130 Ah Lithium Ion Battery.

Battery Charger

For a battery charger, we will be using the iMax B6 is a rapid charger.

This charger will safely charge our battery to no more than 12.6v and will shut down after charging.

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.
