Is that really how much a 400W system can power?

Depends how much draw, how often, how much sun hits it, and how much battery you have behind it.

It's like a hose filling a bucket. A lot depends on how big that bucket is, and how fast you pour out of it.

LiFePO4 150Ah, but a lot depends on the goals of the setup.

360w ones here in NH/VT for $75 each. But they do not come with all the charger, cables, and accessories.

Pre-discount price for me shows up as 266, when I try to apply the code I get error message: the total after discount does not meet minimum purchase amount.

The 280ah one for $230 is a great choice. For most uses you'll need an inverter (from DC to AC current...like this one: https://www.aliexpress.us/item/32...06530.html). Not a sponsor

Are you logged in or is yours a new account? Sometimes Aliexpress has lower pricing for new customers which is why you may be seeing a lower price. The threshold of that coupon is $280 or more so it won't work if you are seeing a lower price.


You can try coupon USDEAL44 ($44 coupon) or RDT32C ($32 coupon) and it should work for you.

Most solar panel manufacturers will claim 400 watts of panel will get you 2000wh per day (thats 5 hrs of perfect conditions) but in the real world, expect about 1500wh on average per day. I can normally top off my 1500wh pecron power station from close to dead to full within 1 day of good of sun with 440 watts of portable ecoflow panels.
