PV Panel output voltage
On the battery side, it is the battery which sets the system voltage. The MPPT takes the panel voltage and converts it to a charging voltage which is higher than battery voltage in order to get current to flow into the battery, the voltage is reduced, the current goes up, and the power remains the same. But the battery chemistry will be ...
How Series Vs Parallel Wired Solar Panels Affects Amps & Volts
Solar Array Volts & Amps Wiring Diagrams: This diagram shows two, 5 amp, 20 volt panels wired in series. Since series wired solar panels get their voltages added while their amps stay the same, we add 20V + 20V to show the total array voltage and leave the amps alone at 5A. There is 5 Amps at 40 Volts coming into the solar charge controller.. This …
How to reduce solar panel VOC (Important!)
The second part is fully controllable. Most of the trouble from overloading a solar controller occurs when you string too many solar panels together. For example, if your solar controller has a maximum voltage of 150 volts, and each of your solar panels produces 36 volts, and you string five panels into a string, you get 180 volts.

Solar and high grid voltage
To avoid this occasional issue, your local electricity distributor needs to set the transformer to a relatively high voltage. However, if the distributor sets the transformer voltage too high, houses close to the transformer may sometimes experience voltages above the maximum allowed 253 V, which also risks damaging appliances.
