Harvesting the power of the sun

We have set up a new configuration to test the solar charging of LFP batteries. Two solar panels (217Wp each) are in a serial string to charge a 48V/90Ah battery pack made of 4 pcs of LP12V 90AH batteries.

During a sunny day in October, we are able to gain more than 2 kWh of energy from the 2 panels. (38Ah at 53V = 2kWh)

Our tests have a multiple purpose: to test the solar charging, to examine different solar controllers, to study the charging of the LFP batteries and finally to make a working solution to disconnect from the grid for ever.
