Free QuoteSolar panels generally fall into two voltage categories: 12V and 24V. A 12V panel can be connected directly to a 12V battery, and my understanding is that the panel voltage is pulled down to the battery voltage so it does not destroy the battery (18V is too much voltage for charging a
Free QuoteThe BN series needs solar voltage to be at least 2 volts over battery voltage so at least 16 volts on the solar input for a 12v battery across the full charge cycle, excluding equalisation voltage if its an open flooded battery. With the Vmp at 20.2 and VoC at 22.9 from a single panel that''s really not a lot of headroom.

Free QuoteIt all depends on what inverters you are going with. If you are on a string inverter these are usually voltage limited, so you generally want lower voltage panels so you can string more of them together. but of course this also means larger wire and that can be a significant cost increase if you move up in size too much.

Free QuoteHigh voltage battery charge controllers tend to cost more, so understandable a battery based all in one has lower max PV voltage. An expensive brand, Sol-Ark, takes high voltage PV. There are separate 600V SCC, but not cheap.
Free QuoteWhen configuring your array, your Voc should be about 10% below the MPPT input limit to allow for cold temperature voltage increases. An MPPT SCC will convert the solar panel power into battery charge voltage and corresponding amps. 400V at 16A is 6400W. 200V at 32A is 6400W. Same thing.
The appropriate solar charge controller does the matching. There ARE boosting ones (for battery V > solar V), but rare and expensive last time I looked, unless you build your own. Just FYI if your solar panel is rated at 100W, you can usually look up the actual output voltage and current at that power rating for your panel.
It's not. It's continuous. If your battery is full, the PV is still converted to battery voltage, but the power may go directly into the inverter @ battery voltage to be converted to AC to power loads. It is the Sol-Ark, hybrid, so hopefully it powers load first, then batteries. You must log in or register to reply here.
Choosing the right voltage for your solar battery setup can make a huge difference in your system's overall performance and cost. Basically, you have three main choices—12 volts, 24 volts, or 48 volts. So, which one is right for your power requirements and the needs of your solar power system?
No. less efficient. The bigger the voltage difference between PV and battery, the less efficient the conversion. The only benefit of higher voltage/lower current is reduced wiring losses, particularly if you have long wires between PV and MPPT.
To charge a battery the applied voltage must be at least equal to the highest voltage the battery reaches. In this case either the PV panel voltage must be as high as desired or you need to add a boost converter. I'll deal only with the direct PV panel connection.
