the best way to connect 30v panels to 12v batteries?
Regarding maximum array voltage--The issues: There is the maximum input voltage of the charge controller. 140-150 VDC is very common for the larger/higher end MPPT charge controllers, and when you take into account cold temperatures and the fact that solar panel Vmp/Voc (voltage maximum power and voltage open circuit) rise in cold weather, rough Vmp~100 volts (STC-
Solar Power Electricity
So for example, a 12 volt 60-watt solar panel measuring about 20 X 44 inches has a rated voltage of 17.1 and a rated 3.5 amperage. V x A = W 17.1 volts times 3.5 amps equals 60 watts If an average of 6 hours of peak sun per day is available in an area, then the above solar panel can produce an average 360-watt hours of power per day; 60w times 6 hrs. = 360 watt-hours.
Renogy Rover 60 12 Volt to 24 Volt Update
When it comes to solar power the "system voltage" is dictated by the battery array. the output from the Rover 60 comes in through a MC4 connector gland on the cabin into an automotive fuse bar rated for 12 to 48 volts DC power. 12-20. We then used a new pair of moderate-gauge wiring to connect the output side, which is now 12 volts

Weather Resistance: Look for panels with a durable design, rated for outdoor conditions. An IP65 rating is ideal for protection against dust and water.
Panels producing too much voltage
Assuming you have a 12 volt battery panel the voltage on a MPPT controller, panel voltage input will be between Vmp (17 volts) at full power, and goes up to VOC (21 to 22 volts) as charging stops. PWM input voltage will be roughly the same as the battery voltage at full charge, (battery voltage + 1 volt), and as the battery approaches full charge the panel voltage
