How to build a Portable Solar Power System DIY (Premium v1)

12 volt DIY system with 300w solar, 100Ah battery and a 1000 watt Inverter*

Recommended Components (scroll to bottom of page to see what products I recommend in this build):

  • Plastic box to mount MPPT, Inverter and components.
  • 300-320 watts of solar panels
  • ​35A MPPT charge controller with Bluetooth
  • 1000W , 12v Inverter*
  • 12v, 100Ah LiFePO4 Battery*
  • Battery Protect DIY board and 500A relay
  • Battery Temperature monitor for MPPT
  • 200A circuit breaker
  • Battery monitor with Bluetooth
  • For links and more detail see below

This system is a beast if you want to make your coffee in the morning and have multiple devices for your kids! It is somewhat portable on a roof rack on your car or RV also with a trolly you can transport it to or from your tent. It can handle a solar panel array up to 500 watts, also it can handle a large (up to ~250Ah) battery bank of 12v batteries and can power a large 12 volt Inverter.

*Watt is depending on solar panels and Inverter size will be limited to battery size.

*High watt Inverter will drain your battery fast depening on use so monitor and protect your batteries from depletion.

*Inverter check so AC and outlet is for your country.

(Watt=W, Amp=A, Ah=Amp-hour)

Picture on top showing version 1 (v1) of the box, it is a little small so I recommend a better larger (v2) below.
