Hi guys I currently have the above inverter mated to two 48v/200ah battery bank. The charging is done by grid or generator....I will be getting 8 panels of 300w...my question what will be the default behavior of the easysolar...will it mainly charge the battery with pv power and use excess power for the loads(what I want...to reduce grid dependence) or do I need to get extra accessories to achieve this. Please help me am a noob...
