I say don't overthink it. Go ahead and buy three off the shelf 12v lifepo4 batteries and run them in series. (Just make sure the bms they use allows for more current then your worst inrush currents) Then buy three cheap voltmeters, hook one up to each battery and mount them on the dash...

Yank the output wires off of your 24->12 step down converter and run those directly to your new lights. If they power up like they did with your bench meter then they probably draw more power than your converter can supply (while it's also supplying all of your other 12V needs). If that...

I have piloted a solar powered boat built by the Bortons' company and it was really fantastic! https://www.solarsal.solar/ But of course they have a normal battery system and don't have the issues created when skipping that step. Like some others in this thread I am skeptical about...

I've driven past the solar farms off of rt 36 for years. They put up all of the racks years and years ago and never put the panels on them. It always seemed odd to me that they'd put in so much money but not actually make it functional. It seemed like there was some sort of scam going on...

I'm interested in playing around with an IQ7 microinverter and I'm not sure how one connects to it. Specifically, what hardware was involved that allowed you to update the firmware on yours? Do I need that $700 box or is there some other method? And if I do pay $700 for a gateway can I use it...

I use this when I'm topping off a 24v bank. It's gentle and takes a long time if you have a lot of aH to fill but it works. https://www.amazon.com/LiFePO4-Battery-Phosphate-Rechargeable-Protection/dp/B0CF62DW36

Off grid systems can be pretty safe in this respect, even ones built by folks you might not want to trust. But if you're grid tied there are a myriad of possible issues you can't easily sidestep. The smart power meter is a glaring example.

Build a greenhouse around your hot tub and you get double the bang for your water heating buck!

The larger the inverter the larger the amount of energy it wastes around the clock even when there is no load on it. For that reason I always select the smallest needed for the job, especially on a small system. But that brings up the larger issue here- you need way more panels than the 600w...

Charge each battery independently and fully and let them sit for at least an hour after the last one is removed from the charger. Measure the voltage of each battery and make sure that each one is within a tenth of a volt of 13.6 volts. Then and only then can you stack them back into your...

This is a 15a plug. I believe you need the larger 20a style in case you plug something big into it. You can tell which is which by the extra notch in the full power one. 3000w/110v= 27.27a

You state that the comms are likely for: Coordinating charge termination That's where I think the comms would stop the issue the OP has found with his system.

Epever says you need to address them differently and wire them together when they are used in parallel, presumably so that they don't have spikes like this. It appears as though you haven't got them sharing data so I would expect the issues you are seeing. If you turn one epever off does...

Unless you plan to put your power into their grid the only answer you should offer this person would involve sucking on a specific appendage. Followed by an armed escort off of your property. The power companies ONLY have any say over the grid and anything that connects to it. Anyone from...

Rectifying power supplies can be very efficient but generally only in a tight design range. Rectifying power supplies that are meant for a wide range of loads are always a compromise of a design which bleeds energy at most power levels. For this reason, things like the wall worts we all use to...
