all right so now that we kind of reviewed a little bit the why of what we did here's what we did so specifically the first thing was we needed to have a large enough battery bank to be able to run this inverter and also to run now the ability give the owner stay an anchor longer running the water pump the lights whatever he was needed to be able to stand at an anchor or at a dock that has no AC power and try to avoid running the generator as much as possible so we installed 2 L 16 AGM batteries in this configuration we really try to have the batteries together but we just couldn't make it the owner didn't want us to actually have the batteries right together for lists and so we had a compromise where we put the two batteries like this you'll notice L 16 batteries are six volts so we had to wire them obviously in series notice we actually actually heat shrink you know read at the right place red here black here that's the series jumpers we've got net pauses negative on one end positive on the other and so we've got now this is effectively his house tank and this was easier because actually oddly enough it was actually came with our t3 battery banks there's a port battery bank for port engine starboard battery bank for starboard engine and there's a house battery so we just increased the capacity these AGM batteries ideally we'd want to have them in a box but in this instance we couldn't so we ended up make sure there was caps so nothing works short and those batteries can't leak so we put these big heavy-duty straps so they can't fall you'll notice them some really good serious tie-downs we always worry about worst-case scenario what happens if you're really big following sees the boat is pounding you're going fast we don't want these batteries that way a hundred and twenty pounds to move at all so that's one of the things we did the next thing we did is we actually found a pretty creative place to mount the inverter the inverter is right down here and it's going to be out of the elements never it's going to be nice and dry and what we ended up doing is you can tell actually the inverter is actually drawing power directly from the battery bank and not from actually the DC District and that's really essential for an inverter charger because it's not just a load it's also charging and all charging circuits should be directly connected to an undisturbed so we ended up doing is installing a dedicated fuse for the inverter a dedicated switch for the inverter charger and then in turn that's the DC side of the circuit and you'll notice that the fuse is actually right at the beginning of the circuit and also we always install its spare fuse in case the fuse blows because the Class C fuse is not easy to source and so we always leave that I mean I honestly rarely see a Class C fuse blew on an inverter but if it does happen because it's also used not just for an inverter but a charger it's really convenient to have for the owner to have a fuse right on board the AC basically goes from the inverter all the way to the channel and what we did here is we divided the AC panel in two parts a non inverter AC panel and an inverted AC panel the inverter AC panel is going to run the microwave the coffee machine the entertainment system outlets things that the owner is maybe going to want to run off of the batteries via the inverter and then there's what are called non inverter loads so like for example the water heater too much power for an inverter to stovetop too much power all those other devices are going to be simply run either from a seashore power or generator but not the inverter and then the last thing we did is installing a battery monitor and the battery monitor component of the install here is a few things one is we have what's called a shunt a shunt is like kind of a choke point it allows the batteries the battery monitor to actually measure all the current that's going in and out of the batteries so it measures current both directions and that's really useful to know what is the loads on the battery and what is the charge rate on the battery and the other thing we did is we also installed the voltage sense for the battery monitor directly of the batteries some people take shortcuts and they install them down at the DC distribution further down thinking they're being creative but what that can do is if you're ever lose one of those fuses below you think you have no more batteries because you look at your battery monitor and it says zero volts and you think you have no more batteries but in a it's you're measuring voltage too far away from the batteries and you're just realizing that a fuse may have blown downstream so it's really essential when you're doing a battery monitor to actually go directly add the battery for voltage sense and that's basically what we did in this engine room you
