![]() ![]() The relay contacts must close and provide a low resistance without the benefit of any arcing for cleaning. A momentary, dash-mounted switch can also be added to provide a “jump start” for the engine, from the auxilliary battery. The 200 amp version is not a continuous duty unit and requires an Isolator – diesel controller to prevent it from over-heating when it is used for continuous duty. It is installed between the two batteries, connecting them together for charging. The Isolator Relay provides a simple, reliable and cost effective means of isolating two battery systems. The 200 amp Isolator Relay is designed for heavier duty applications. These relays have been designed and are built to meet these demanding conditions. In this application, these relays are required to operate with almost no voltage across their contacts and carry currents ranging from milliamps to hundreds of amps. Also a solar panel with multi stage change controller for times not connected to shore power.200 Amp Battery Isolator Relay Specifically designed to be used to isolate two battery systems. I’m running a TRUECHARGE 20 multistage charger to keep them all in top shape when connected to shore power. or a manual battery switch to connect the banks.ġ) the pair of 12v marine couldn’t last 24 hours running the fridge.Ģ) the two 6V ran the fridge for 3 days after I’d drained them to 12.3v.ģ) the 12v wouldn’t run the microwave for more than 2 minutes or handle the starting load of my smallest 120v compressor.Ĥ) the 6V have no problem with running the microwave for longer (even when already drained) and can also run the compressor fine. If I decide to use the rig as a generator I’ll just add a switch to keep the sure start relays closed. To buy an ACR over, I’d get the Blue Sea 7620 rated for 500 A output. I could dig deeper into the alternator wiring to solve this, but I’m taking the path of least resistance for now. With the alternator wired to the starting bank, that problem went away. ![]() this was knocking out the inverter which has an input limit of 15 v. ![]() Alternator output was peaking at about 15.2 v until the ACR connected the banks. I’d planned on wiring the alternator to the house batteries, but I found the alternator output feedback is through the OEM wiring to the starting batteries. Any time the alternator is pushing more than 120 amps, a large chunk of it is recharging the starting batteries (which doesn’t go through the relay). The house batteries usually only draw about 100 amps peak. It’s rated to handle 215 amps for 5 minutes. The weight would be the same and I could run the engine for a bit if I needed power to run the AC.Ĭlick to expand.I’m using a Blue Sea 7610. I would probably be happier with a big alternator, 3000 watt pure sine wave inverter, and four 6 Volt batteries. I have a 2.8 kW generator under the new van which weighs about 130 pounds installed. That is a recipe for boiled batteries if not programmed properly. Be careful when you set the final stage voltage if you draw power from the batteries at the same time as you charge them. You really need to pick a charger that has at least 3 stages, has a battery temperature sensor, adjusts voltage based on technology, and is quiet. I ended up removing the original 6 amp battery charger the DC panel had built into it because it would take too long to restore the batteries and it did not have any intelligence. Those batteries were happy to suck up all the power the alternator could put out. I never lacked power with that system except when I let it get too low and wasn't able to charge it with the alternator (tripped breaker issue). My other van had two Trojan T-105 Plus batteries, a 25/50 amp charger, and a 2000 watt pure sine wave inverter. The 6 Volt batteries and a good charger are a whole other story. This may be handy if I put in a 2nd alternator or swap the one I've got with a 300 amp job. ![]() Bikesmurf: Which VSR are you using? It seems that you've got quite a bit more current passing through it than I've seen available. ![]()
