Hello, I recently purchased this:
https://www.droking.com/dc-power-supply/dc-boost/900W-Power-Supply-Module-DC-8-60V-to-10-120V-15A-NC-Voltage-Regulator-Adapter-Boost-Converter-Constant-Voltage-Current-Driver-Module-High-Precise-Adjustable-Output-48V-24V-12V-DC-Power-Supply-with-LED-Display-Voltmeter-Ammeter

My goal is to boost my ~20v solar panels that are hooked up in parallel, outputting roughly 12amps to 48v to plug into a MrPow solar charger to charge my 48v battery setup.  I cannot seem to get this to power up the MrPow at all, I’ve also tried to hook it up directly to the BMS to no avail.  I’ve increased the output voltage to around 56v and I get an accurate reading from my multimeter stating that, but I’m not sure if maybe it’s not outputting enough amps?  Any help on how to set this up properly would be greatly appreciated, I’ve read the manual several times already and tried lots of things.

Thanks!
