You might not need an interconnection agreement if the inverter cannot export to the grid, such as the 6000xp.

Solar and battery tax credit is currently through 2033. I say buy batteries now, and replace in 2033 if the credit is not extended.

Buy from Current Conected.

Off grid, you need batteries. Consider cost of interconnection towards cost of off grid system.

How much are the high voltage batteries? Where can you buy them?

Eg4 18kpv, sol-ark 15k, 12k, 8k

Eg4 powerpro is not that much more than DIY. Markup: cost of avoiding getting scammed by the wild west on alibaba.

Victron orion tr 48/12. Assumes your house battery is 48v.

A CT measures the power flow. If you put it on the line to the meter, the inverter can zero power movement across that point.

"Grid tied" means can export power to the grid. Almost all AIO can take power from the grid, just like they can take from a generator. The grid is a big generator.

Grow the system to what size? Design your eventual system, and figure out how to install that in stages. I'm guessing you will want one inverter, and grow the system by adding panels and batteries over time. Victron makes good equipment, but is not typical for a house in the USA. Note...

Then you want to maximize self consumption. You can do that with an off grid system. 6000xp can store all the power in the battery, and then take from grid when battery runs down. Gives you grid backup, but you can't export to grid. For the cost difference between 6000xp and 18kpv, it can pay...

One powerwall is fine if all you need is 13kwh. If you need more battery, components start making more sense. Pay for inverter once, and add as much battery as you need.

Does not look like the inverter is battery ready. Consider replacing the inverter with an eg4 18k or sol-ark 15k. 3000 or 6000xp may work. A little trickier to implement charging from ac pv. 3000 or 6000xp would easily work if you are willing to give up exporting, and buy enough battery (20kwh...

I can see 130ah batteries becoming popular to stay under the 20kwh limit. Or 97ah for 4 racks.

Breaker protects the wire. As long as you have appropriately sized wire. I would set the bms discharge rate. Check temp when drawing the max. Install the class t fuse.

Function Port, pins 11 and 12. Don't know how many amps are available.

Rated for 100 amps. How big a battery? Class t fuse too?

Post what equipment you have.

I belive the eg4 3k can supplement grid power.

IMHO, the tech is more likely to be right than the supervisor. Replacing the inverter is one piece of replacing the entire system. They could send an electrician out to replace the inverter. If that doesn't work, they then can send a crew to replace the panels and attach them to the new...

Took me less than a month from when I ordered the parts to getting it working with my inverter. I only had time to play on weekends, and I took it slowly (measure twice, cut once). I would have spent at least 2 weeks installing a COTS battery (wire, fuses, switches, initial charge, building the...

Eg4 powerpro (original, not indoor model). If comms doesn't work, just run in voltage mode.

Keep the old one in a Faraday cage as your truly emp hardened 15k. If the hardened one fails, you have a working one (until the next nuclear bomb goes off). 2 is 1, and 1 is none.

Don't believe SOC until you KNOW the battery has charged to at least 55.0v. Set start cell balancing to 3.38v Set Cell OVP to 3.640v Set Cell OVPR to 3.639v Charge at 58.0v until the first BMS cuts out due to Cell Over Voltage. Note the voltage at cutoff, and which BMS is cutting out. Charge...

Climate change is a lot worse than I thought.

Batteries.

If you are DIY a solar power system, the additional work to DIY a battery is not much more. You back out the research part because that is required whether he builds or buys. Also by DIY, you learn a lot about how batteries integrate into the system. Plus, safety: proper wire sizing, class t...

Setting in inverter. Setting in bms (last resort).

Just because you had a bad experience....

The idea is to keep battery power at the battery connection of the inverter. Turning off the breaker doesn’t do that.

Poster has a special case of wanting to start with a 12v system and grow to a 48v system. People raised the concern of keeping balanced 12v batteries in series. The easy solution is to build a battery and reconfigure.

https://www.18650batterystore.com/collections/lifepo4-prismatic-cells With that many cells, why not a 48v system?

Can I plug 150km of wire into an mppt? I wonder how much power I could get.
