Hello.
A single 72 cell photovoltaic solar panel rated 400W - 40V - 10A - 2m² connected to an automotive 12V nominal lead-acid battery and a 500W load for a couple of hours.
The photovoltaic panel can trade its delivery of voltage/current to a certain point into a battery, but what to expect ? Early failure of the battery as there is no voltage regulator/limiting ?
What is missing to make it work as it should ? A 10A charge controller ?
