I have a little house in a village in the Solomon Islands fully powered from solar 12v DC.
Panels are crazy expensive there due a few monopoly vendors, so I bought a used 250 watt panels in Australia and shipped it over.
However what I didn't account for when making the purchase was that the panel had an output of 50 volts. It come off a house roof top solar installation designed for 240 v and grid, not 12v DC.
The PWM regulator, despite being rated well in excess of the amperage output can't handle the peak voltage and the fuses burn out.
Given the difficulty and expense of getting panels in the Solomon Islands I'd like try find a solution to use that panel if I can.
Is there anyway I can make that possible? For example can I reduce the output to a lesser voltage somehow?
Any advice would be appreciated.
