Since the two main battery systems used in this guideline are lead acid-batteries and li-Ion batteries the inverter connected to the battery systems within this guideline is simply described as the battery inverter.
battery grid connect inverter if retrofitted to an existing grid-connected PV system.Figure 3 shows a system w th two inverters, one battery grid connect inverter and one PV grid-connect inv rter. These systems will be referred to as “ac coupled” throughout the guideline. The two inverters can be con

put as it requires a reference to ac power (typically the grid or another ac source). Therefore, a PV array cannot power loads via a PV grid connect inverter without add onal equipment. They typically contain an MPPT for controlling the PV array output. Note: Considering the two
ect inverter (hybrid) has both a PV inlet port and a battery system inlet port. It will also have a port for i erconnecting with the grid and an outlet port for dedicate (specified) loads. Hence it is capable of operating with or without the grid. The multimode ability is required for the system
