Retrofitting old energy storage systems with solar cells

Solar + storage systems fall into two buckets; AC coupled and DC coupled. In DC coupled system current flows from the module strings to a hybrid inverter or charge controller then to the batteries for charging. When power from the batteries is needed the hybrid inverter or battery-based inverters converts the DC. . Most existing PV system are tied into the main service panel of the building. In some instances the point of interconnection is on a subpanel or a load-side connection of the service conductors. Whatever the case, to retrofit an AC. . If the retrofitted AC coupled storage system is to be operational in a grid backup mode, it is important to ensure the PV inverter and battery inverter communicate effectively. If they do not, the PV system could. . For information on the tax incentives available to storage systems see our previous article HERE.
