Make sure that the wire is clamped properly and that it should not rub against any sharp edges or corners. If some wire needs to be changed, make sure it is of proper rating and type. 3. INVERTER The inverter should be installed in a clean, dry, and ventilated area which is separated from, and not directly above, the battery bank. Remove any excess dust in heat sinks and ventilations. This should only be done with a dry cloth or brush. Check that vermin have not infested the inverter. Typical signs of this include spider webs on ventilation grills or in heat sinks. wasps’ nests Check functionality, e.g. automatic disconnection upon loss of grid power supply, at least once a month. Verify the state of DC/AC surge arrestors, cable connections, and circuit breakers. 4. SHUTTING DOWN THE SYSTEM Disconnect system from all power sources in accordance with instructions for all other components used in the system. Completely cover system modules with an opaque material to prevent electricity from being generated while disconnecting conductors. To the extent possible, system shutdown will not be done during day time or peak generation. d.
