I am looking for a low voltage recharging hub to go between 2 × 80w solar panels and a 120ahr deep cycle battery. I wish to run 4 × 12 v led light out puts and include 4 × 5v usb charging ports and meter to include battery level. and possibly a 12v 20amp fridge for a short period – 1-2 hr).
There appears to be nothing on the market re this so I may need to build it. Any ideas re where to look or how to build it?
Regards Allan

Hi Creative,

First, you need to consider that solar energy has only 5/24 capacity factor which means it can only charge up to 5/24 in a day.

Considering your components, then calculate your required energy VS energy collected by solar charging.

You can make use of the schematic diagrams provided by the link below:

You can save and customize the ref. designs provided or you can create your own design there for free.

Hope it helps.

Best,
Neil
