if the ebay extra $50 coupon code is still working you can get the refurb Delta3-1500

for $450+tax from ebay

bought it last week, running it now

has some quirks but for the most part will be fine

note that the way they do 1500w is a 51.2 volt 30amp lifepo4 battery inside

the 500watt charging is only at higher voltage, if you use 12 volts it's like 8amps max, so you'd need solar panels in series

totally silent in grid bypass mode, haven't tested the 15ms switchover yet

ah they took off their 15% coupon

it will be back if you wait another week or two, they have tons of them

maybe around july 4th?

the problem is I dunno if the ebay $50 code is going to be around that long or even if it still works

1 item $587.06
Item discount -$88.06
Shipping Free
Coupon -$49.90

= $450 + tax

you can test the extra code like this

The delta 3 plus
  • It's an updated design, new technology.
  • 2 solar inputs
  • 1kw battery
Delta 3 premium
  • It's a delta 2 with upgrades but similar design. They fixed the noise issue.
  • 1500 watts battery storage
  • Only 1 solar input
  • this should be a delta 2 premium, because the delta 3 is different design.
