Thank you for this training. Very educative.

Please ensure that both solar panels are not shadowed by grass and tiles/bricks, as visible @ 5:46. Small patches of shadow tend to make a rather large difference in output, depending on the type/quality of the panel.

I totally agree having run a typical test.

Hello again,

Some people on internet trying to use some psu laptop adapters dc power supply and use pwm or mppt charger unit then charge batteries and all of them failed. Somehow power supplies close itself. Some days mppt tried took all current and psu close like shortcircuit protection.

But you use samt thing only difference is these Chinese boost converter. Can put server psu directly pwm charger? Or put mppt charger without boost converter.

Use the external capacity tester for both experiment, use same or similar battery bank, similar charge level

I have a 300watt panel and a 12v battery i I'm having issues using pwm solar charge controller for charging the battery because the panel produces 42v will using an mppt charge controller work?

steaphenaugustine

Using a 12volts panel on pwm would person better than mppt

Incomplete video you cannot just hook up any panel with volts and wats details

The controllers protect the batteries/charging, not the solar panel.

Unfair comparison. 24v pv to 12v battery. Try 12v pv
