Mixing Solar Panels Mppt

When mixing solar modules is important to remember that it is not the wattage of the modules that is important to consider.

Mixing solar panels mppt.

The result of the multiplication must not be higher than the maximum pv open circuit voltage as listed on the mppt datasheet. Not planning on touching that one. Then multiply that by the number of panels that are in series in the array. This allows you to add additional panels to an existing battery based system and still maximize the output of both sub arrays.

Mixing solar panels of various voltage or wattage or produced by different manufacturers is a frequently asked question by most diyers. Current total wattage is 900w. One is 2x325w 72 cell panels in series feeding a victron 100 50 mppt. First look at the datasheets of the solar panels to see what their maximum open circuit voltage is.

With the matching outputs of the charge controllers you can now combine 2 or more power sources of equal voltage together in parallel and the current from them adds together. Though mixing different solar panels is not recommended it s not forbidden and things would be ok as long as each panel s electrical parameters voltage wattage amps are carefully considered. I currently have 2 solar arrays. Mixing solar panels in parallel total connected power 150w 150w 150w 150w 600w unlike connection in series if among modules connected in parallel there is a module of power output lower than the output of the other modules this might not affect seriously the total power output of the array provided that this module has equal to the other modules rated voltage.
