Also a solar panel with multi stage change controller for times not connected to shore power. I’m running a TRUECHARGE 20 multistage charger to keep them all in top shape when connected to shore power. Smart battery isolator 300 amp manual#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. Seller assumes all responsibility for this listing. Report item - opens in a new window or tab. ![]() Smart battery isolator 300 amp generator#If I decide to use the rig as a generator I’ll just add a switch to keep the sure start relays closed. Dual Battery Smart Isolator 12V 140 Amp Voltage Sensitive Relay VSR Smart Switch. To buy an ACR over, I’d get the Blue Sea 7620 rated for 500 A output. Find 4 Position, 12 Volt, 300 Amp, Dual Battery Disconnect Switch at MSC Industrial Supply, serving the metalworking, safety, and MRO industries for over 75. 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. Unlike Dual Battery Isolators, The IB200 Does Not Create Any Voltage Drop To The Secondary. That is a recipe for boiled batteries if not programmed properly. IB200 Relay Handles 200 amps continuous and 300 amp surges. 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). Smart battery isolator 300 amp plus#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. Terminal covers (pair) for a pair of rubberised red and black terminal covers.Īlternatively we also have a pair of Quick Release Battery Terminals, for applications where you may want to disconnect your battery on regular occasions.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. If you also need battery terminals see the following: Marine Battery Isolator Switch / Kill Switch 200 Amp ![]() Ideal for marine applications.īattery Isolator Switch / Kill Switch 150 Amp Very high degree of waterproofing (IP68). Overall diameter is 71.8mm with 4 x mounting mounting hole centres of 56.24mm. With switching positions of: on and off and then the key can be removed at the off position.Ĥ50A intermittent and 1000A cranking current. These heavy duty waterproof marine battery isolator switches are rated at 300A 50V DC continuous current, 450A intermittent and 1000A cranking current. This battery isolator switch is designed to cut off the power to the battery quickly in the event of an emergency or to ensure no unexpected power draw from the battery during vehicle storage. ![]() This is a high quality battery isolator switch for camper van, motor home, car or marine use.
