Yes, I don't see why a lead acid battery would not do it. You will still get a spark, but no BMS to flip out.

Minutes ago, rainy day so not much happening here. 34 watts.

5kWh is likely not enough battery if you want to run air conditioning, unless you supplement with something. If you have enough panels you can run the A/C while the sun is shining, but 5kWh of battery might only last about 5 or 6 hours for your small A/C, maybe a little more depending on how...

If you only want to monitor the 250/85 you can do that through bluetooth ... nothing else required. If you want to monitor power in and out of the batteries, you would use a shunt.

The manufacturer of my last drop-ins says to float at 3.45v per cell, so I might do that. Currently set lower. But I Don't really care, My system rarely floats.

Can you clarify where the shunt is installed? Maybe a simple line drawing? or even some photos?

I haven't had any false alarms. Perhaps a loose connection?

If you only ever spend 2 days at a time here, you have 6 days or more for your batteries to charge back up after a weekend of use. I don't think you need to go crazy on the solar. I would do the battery upgrade and see how things go with the rest of the system.

I don't really want the wood backing to absorb any heat. ;) A light coat of flat black on the metal sheet, the side facing the heat source, should reduce potential to radiate any heat back to the inverter. The space behind the sheet should give a path to dissipate more heat rather than...

Issues? The 12volt batteries can become out of balance with each other since the BMSs do not talk to each other.

No.

You cannot use the "Daly" logo anywhere on your product. That likely also applies to using it in advertising and marketing materials for your product. So, when you list all of the attributes of your product in sales info, you can't say it uses a "Daly" BMS.

If I override the timer in the evening I can hear the tank elements running, so, I know we are saving some usage.

I don't see the test as flawed at all. The alternator has a built in fan. That's why it overheated at low RPM and not at high RPM. And air circulation inside an engine compartment is not guaranteed at low RPM.

Copy that. I just looked at my settings. I made some adjustments when I lowered my upper charge limits and must have missed that. Was set at 4%. Working fine.

Installation manual shows flaring instructions and no reference to a plug and play lineset. ¯\_(ツ)_/¯ Perhaps they have updated?

Does the hand held multi meter verify the voltages you see on the BMS?

I suppose I would want to know how far off from factory spec the cells are to make a decision on their health, but honestly, you couldn't pay me to mess with used batteries at this point

It's been a real long time since I ran a car out of gas. And one of my cars doesn't even have a gas gauge.

I just bought some 24 volt light fixtures that draw 11.5 watts. https://www.ebay.com/itm/144570828498 Even if I put 2 of them on a switch it would still only be 1 amp draw. I'll let you guys know what I find when the switches show up in a week.

The Orison has been in development for years. The original idea was a free standing device ... now it is a panel than can hang on the wall or hide behind the couch ... that stores power and can backfeed your electrical panel when the power goes out. Supposed to work in conjunction with a...

Also, the things you circled in green in the photo above look to me like connections for a relay. NC is normally closed, NO is normally opened and C is the common connection for the relay. Information for what controls this relay should be in your manual.

Loose connections after moving it around?

I bet you could find something in here that will fit on that forward triangle to give you some light? RV Skylights

This may be the answer. Also. OP mentioned "Victron 8k watt Multiplus II charger/inverter" and 220v. To get North American standard 240/120 split phase you need 2 Victron inverters linked together, or 1 Victron and a transformer to make 240/120.

I don't believe I responded to anyone in particular. I worked in radio, TV, and movies for 40 years. I was on the inside.

Put a DC isolator within arms reach of the charge controller and use that to make the transition from the PV wire to high strand count wire.

Looks like the structure is raised up a few feet? How close to the coast? Will this panel go under water when the big one hits? I built a self-contained backup system with new circuits to critical loads. This allows me to plug devices into the normal house circuits or the backup circuits as...

My mini fridge uses about 2/3 the power of my full size fridge, only holds about 1/6 the contents of the larger fridge, and the freezer only has room for 2 ice trays. We only use it for drinks and it is not on our solar backup battery system. If I were going completely off grid I would...

It does seem something is wrong. I have a 24v Multiplus 3000VA and it is less efficient when running near its upper limits but I haven't done an efficiency calculation because it seems normal to me. It takes energy to run the cooling fan, but certainly not that much. By the way, your...
