Ok, after a tablet reboot and down load the ao app from Google (3rd time) under my wife's account it now works for all 4 batteries. All are reporting 27 to 28% soc and 12.8v Edit: Charging at 13.3 volts Nd 14 amps and the app agrees? app doesn't have much use beyond that and history. You have...

Yep, that's florida flicker and flash. Remember the late 90's, they tried to emulate Enron and what happened to them. Then the fpl lobbyists wrote an anti solar bill in 2022. Fortunately the governor did the right thing and vetoed it.

Might want to at this thread Questions about "nesting" or daisy chaining bus bars

That will have a major impact on tongue weight. I had to shift a cooler more forward once. Remember 60% of weight needs to in front of the axle or a Coleman gets real squirrelly.

If your taco has tow/haul that can make a difference also

1 of the boxes my aolithium arrived in looked a bit like yours, must be a fed x thing.

Typical residential refrigerator draws 17 amps from the battery bank when it cycles. A 440 aH lead acid battery has bank lasts 16 hours and takes 8 hours to recharge at 60 amps. This is based on measurements I made dry camping in 2016. I suspect your right on the edge with your 200 aH battery...

That was a bit of tongue in cheek. Having worked in electronics and the power industry all my life I know the difference. Here on the board the thinking is VA=Watts. That's why I remind folks about Victron inverters. We can easily forget a 3000VA Victron is 2400 Watts. Saw one vendor today and...

At 48 volt it does allow for more pv, I just have to keep in mind I'm running 12AWG wire to the cc's. Don't really require more then 4kW.

Our GE draws 60 amps from the batteries @ 12.8 volts

For maintenance I use Midnight solar breakers. I have some that are turned off once a week when we change campsites. They have been in service since 2012. Or maybe I just got lucky. Anyways just ordered 8 more for a off grid set up.

Several years ago the rule PWM for less then 500 Watts on a 12 volt system Mppt prices have dropped so much go that way

When the county inspector came out for the electrical inspection he asked why 2 ground rods and why #6 wire. I replied I had the wire and dry sand doesn't conduct well. This was in 2000. Codes were different then. 18 inch direct burial ok. I ran conduit 2 feet down.

Based on cable rating alone, the fuse size would be 325 x 1.25 = 406.25 so a 400 amp fuse. But the Bluesea switch contacts are rated at 300 amps. I'm going with a 300 amp MRBF fuse. Class T might be preferable but I have zero experience with them. I'm also not a fan of cartridge style fuses in...

All the charts I've seen say don't go below 12.2 vdc. This is an old article that still has value. http://marxrv.com/12volt/12volt.htm The only real way to tell soc of flooded batteries is measure specific gravity which for agm and gel cannot be done. Edit. For my agm batteries I try to stay...

Actually I have 4 MRBF fuse holders, 1 for each battery. There is more surface for the fuse holder on the bus bar, therefor lower resistance connection. Prior to this forum I have never heard of mounting the fuse directly to the battery. Also haven't see it in 50 years of working with dc...

I'm going with 2/0 from WindayNation, $41 and change for 3 feet of red and black with 3/8 tinned lugs. It's $ 44 and change from Harbor Freight. Seems to up from there. Edit on ours I leave the charger breaker turned off 99% of the time and solar is always on.

Scc and charger are parallel sources and I've seen no conflicts there with leaving both on. In my case it is scc and vehicle alternator. 50 amp breaker for the scc and 100 amp between alternator and batteries. Batteries are AGM in my case. I'm thinking about posting my RV build here as a...

The inverter you show is not a good choice for a microwave or A/C unit. Low frequency pure sine wave is better. The breaker is also a poor choice.

It's the individual fuse not additive.

No permit is a risk. Especially if you have solar snitches. Some people can't mind their own business.

Ok, I missed something. Bluesea MRBF fuses are sold with ampacities of greater then 100 amp for their fuse holders. I'm using 125 amp fuses one for each battery. Also set up a 300 amp MRBF to feed wiring to the inverter.

Santan claims 1 year warranty on their blems.

5 deg F in showlow this morning so far. It will be similar at the desert nest.

This is why the desert nest is close to the new laundromat. Once a week 1 1/2 hours, done. Also has showers with unlimited hot water.

12 AWG 105 c wire is fine @ 30 a for about 6 feet.

You are just ducking out on triple digits in the valley.

I've have Midnight solar breakers since 2012 between the panels and pwm cc. No problems. Current RV uses breakers, look like many you see on Amazon. Lever to rest and button to test. They have been in service for 7 years with no problems. My experience with cartridge type fuses over the last 50...

What kind of batteries? What I had was solid state battery isolator from an RV dealer. Worked great with lead acid batteries for years. As mentioned above with lithium a dc to dc is needed. I leave the solar on all the time

1 thing I'm considering is set the battery bank up as 24 volt. Means buying a different inverter and dc to dc converter for a few 12V items like the water pump. Move the 12V inverter to the RV for the microwave. Voc for the new panels is 21.8, round it to 22 and 3 panels is 66 volts in series...
