This is so tempting. Pretty sure this is one of the SRNE manufactured inverters Will's always talking about. Sadly I just bought 20kwh of dc-house 48v batteries in the last month and a half.

Last time I looked into these they were not UL-listed, which may be important to some. (They've been claiming listing is "pending" for quite some time.)


Edit: I just noticed the copy on eBay says the following now: "Additionally, it has passed UL safety certification, having undergone rigorous testing in accordance with UL1973 and UL9540A—two benchmark safety standards in North America."

This is a smoking hot deal! I don't need any more but if I did, I'd be all over this.

That's for the batteries, I don't see any certifications for the inverter. Does the inverter need to be UL or some other compliance?

The batteries are 800 EACH on sale! So 1600 in batteries means 400 for the inverter. Find it cheaper elsewhere, I'll wait haha

$800 for 10kwh. lamo. I just bought 4 eco worthy 280ah 12v batteries for $1,212 (last deal that ended on Saturday) + $50 LiTime balancer.

$1,212+ $50= $1,262

$1,262 / 280 ah = $4.50/ah for 48v config.
$4.50 x 200 ah = $900. ok. its $100 more than I stated.

When you power your house you will understand how fast you burn through 10 kWh. I've now got 8 ecoworthy 280s 12v, 4 dchouse 165, and 4 mixed 100ah batts.
