Inverter Installation 1
Story and photography by Capt. Vincent Daniello
Let’s take a look at the first install, shown at right. While the heart of any inverter system is the DC battery bank, cables that carry DC power to the inverter are its arteries and veins. A blockage (i.e., resistance) in any one spot can kill an inverter or even cause a fire. Make sure connections are tight and wires are sized sufficiently (see “Getting It Right,”). Protect those wires with a disconnect switch (1) as well as the inverter-manufacturer-suggested fuse (2). I’ve also installed a DC shunt in the negative cable (3) to meter inverter current draw and a battery-temperature sensor (4) to monitor battery state.
