230 Volt SystemThis wiring diagram is an example of a system of about 500 peak watts which is designed to give a 230 Volt output to power normal mains appliances. The DC wiring is configured for 24 Volts, so as to reduce cabling and controller costs. It assumes that the inverter has a low-voltage disconnect function to protect the batteries from over-discharge. Note that the battery negative terminal and the consumer unit should be earthed for electrical safety. Also note the separate battery fuse which is necessary owing to the potential for very high short-circuit currents.
