Max Distance Between Solar Panels And Inverter

The ideal would be to prepare a room near the solar panels to place the inverter battery bank charge controller etc.

Max distance between solar panels and inverter.

The system is a grid tie 2kw 9 x 230w panels. You will have a 10 voltage drop but since these panels are such high voltage you would end up with a voltage of 16 7 at the charge controller which should be okay. The distance from panels to inverter will be 20 meters max and the distance from inverter to meter box will be 2 meters max. I m going to assume a voc of 37 7 max power volts at 30 240 watts eight amps since that s pretty common.

If you were to feed dc back to the house assuming that the pv panels are configured for the max allowable voltage of 600v the cable would only need to carry 8 5a and could have 3 drop 18v. My installer is supplying 6 mm cable for both connections. The panels quoted are the ibc polysol 230te nominal voltage of 29v and a sunny boy inverter don t know the model yet therefore 29v x 9 panels 261v dc.

The inverter will only generate 5kw max so max feed in current will be 22a. Solar panels generate dc current which is transported through dc wire via a solar charge controller or solar inverter to a dc battery. Power inverters are inverters whose battery is charged from a constant power supply like grid or generator in which the ac voltage is converted to dc and battery within inverter is charged and again the inverter circuit inverts the dc voltage from. Calculate the cable size for a max 2 drop 4 8v over the 300m length.

Power from the inverter is ac voltage and will suffer marked transmission losses. Therefore the inverter should be no more than 10 metres from your power box. Normally batteries should be placed between 20 to 30 feet to avoid loss of dc current during transmission. So you send ac current from the inverter to the house because if you try to send dc current would be very.
