This is a good price. But you will need 1 or 2 more 6 kWh batteries.
The main problem is if you go solar with these and you want roof mounted panels, then it is unclear if you can pass NEC codes like the direct current from the panels being in a conduit with no exposed cables and a rapid disconnect switch for fire fighter protection.

Is this the lowest so far for new? (not counting the Home Depot mistake)

Are you sure it was a mistake? Wished I would have bought more....

i think so, especially for me, considering no sales tax. i think the previous low (outside of home depot deal, which only lasted an hour), was $3999. this $3789 is still a bit too high for me, because i don't really need this, but it is encouraging that the price dropped below 4000 for the first time, by $120.

i don't really need one of these, but i do want one. if another home depot priced deal came along, i would buy without hesitation for a price like that.

No problem passing NEC code. APsmart RDS-S-PLC on every solar panel, APSmart transmitter outdoor kit, and everything THHN/PV wire 10awg in metal conduit. Passes NEC code.

Like HarryE3231, I also passed inspection. Full NEC compliance. You are right about needing 1-2 more batteries.


It's been pretty great since the cost of installing my fourteen 360W panels + this generator + 2 batteries was roughly the estimate we were given for a Generac to be installed. Sure the Generac can keep you going indefinitely regardless of weather, but it's a hefty upfront cost + continued maintenance + the cost of natural gas. This is a single large upfront cost, and then continues to save me money over the years.

What was your total install cost?

Micro Macro. I would be thrilled if I could pass inspection here in California with the 12 to 14 420- watt panels that I have room for? What did you have to do to pass the regs. Certainly don't want to mess with insurance coverage these days. Could you please tell us some more about your panel configuration.

Ecoflow Delta Ultra Pro $4,883.81
Ecoflow Battery #2 $2,344.68
Ecoflow Battery #3 $2,039.15
Solar Installation $7,190.00
Total: $16457.64 - take away a 30% federal rebate for solar and storage - new total: $11,520.35
I was quoted ~$12k for a Generac install. My house came with a 10 circuit transfer switch from the previous owner (would've only been a few hundred more to install if it hadn't) and I keep all 10 circuits on the Ecoflow March-October virtually full-time. I reduce the load Nov-Feb because of limited sunlight.

Do these qualify for the tax rebate? Is there still a tax rebate? How long of a power cable can I run to the ecoflow from the solar panels?

OK so for starters, I relied on the solar installer I found to make sure I was in compliance. That was basically why I hired them - and it wasn't easy to find someone willing to undertake this task. Most solar companies want to do a routine install to hook you up with their inverters to the grid. Their financing department is usually bigger than their technical staff. The guys I found (RPS Solar in Monmouth County, NJ) were basically solar-specialized electricians. They told me "here are the panels we are currently installing, you figure out the configuration you want and we'll take care of the logistics". I can't tell you EXACTLY what they did to ensure compliance, but I can tell you that per your concern that they installed a disconnect switch on the cables coming from the roof. However, the EcoFlow unit has a disconnect switch itself too. FWIW I'm in NJ which seems to have the same module-level shutdown requirements as CA? (https://www.nfpa.org/education-an...ement-maps)

The panels were 360W variant of these (https://www.solarflexion.com/v/vs..._Sheet.pdf). I put 8 of them in series on the high-PV input port, and 3x3 (3 in series, in parallel with another 3 in series) on the low-PV input port. Getting the specs on the panels you'd be using is important to not exceed max voltage (450V on high-PV, 150V on low-PV). Check the panel's open circuit voltage (Voc) and use the temperature coefficient to figure out what the highest voltage is you could possibly get in your location - something like https://energyresearch.ucf.edu/so...rence-map/ and check the "extreme min" temperature.

Maybe you'd find a solar installer comfortable with doing that configuration for you, but mine wanted me to undertake that part since I was using my inverter instead of theirs. This is certainly not a commonplace installation yet - it was the first install of its type in my township and took 3 months to get approval for the permits!

I would consider one of these as well if the price for a new unit was what I feel is reasonable considering other options on the market, including building yourself. I like this unit over building myself if the price was lower.

I may have a solar electrician who was recommended by my roofer who said he will do what you want. I'll let you know what he thinks. Thanks

Yes. 30% tax credit if nothing changes this year.

There are calculators online for determining lengths and voltage drops.
