Hey. If your powers out and you didn’t plan. I can let you borrow a battery powered air pump and a small power inverter that will plug into your cigarette lighter it’s 300w max. I’m in San Francisco. Let me know.
When I saw the stormy weather forecast I set my powerwalls to 100% backup. We haven’t lost power but hopefully will be ready for it if we do.
Have you ever had storm watch kick in?When I saw the stormy weather forecast I set my powerwalls to 100% backup. We haven’t lost power but hopefully will be ready for it if we do.
Yes it does sometimes. Supposed to be triggered by official weather alerts… but isn’t alwaysHave you ever had storm watch kick in?
@BAYMAC You can modulate the minimum storage level in the battery via the app that controls it.
What I was told was take the battery size and multiply it by 0.85. That’ll give you what you can really use. So for you 2048Wh * 0.85= 1740.80Wh. Then divide it by what you have plugged in. You mentioned the two 200W heaters, assuming they were both consistently on drawing 200W each (they won’t) and using 400W. 1740.80 / 400= 4.352hrs. So you’d be able to get about 4hrs 20min with those heaters drawing in their full power. Heaters use up a ton of power, I would just keep pumps on and if your house is cold, maybe just plug in one of the heaters to extend your time.I’m thinking of getting a 2kwh battery for backup. Goal is to provide 24hrs heat and flow. Tank is 65g. I have 2 x200w heater, but don’t know how to estimate total power used in a day. Flow power draw is minimal.
Any thought if this will work? eBay have refurbished Ecoflow delta max 2kwh (not lithium phosphate) for sale for ard $700. For my need 800 charge cycle is plenty.
Ops, didn’t read your comment fully. Yes, your assumption is correct. Now is 4.3hours of heater on time sufficient for 12 hours/24 hours? In the middle of winter , without heat the ambient temp in the living room can get to low 60s.What I was told was take the battery size and multiply it by 0.85.

Yeah they won’t be drawing the 200W each consistently, only when they cycle on. But not sure how you would do the math to calculate usage for that since it really depends on the temps in your home. My 45Gal I only run a 100W heater since it’s normally pretty warm in here.I suspect heater is not going to be on the entire night. It will likely cycle on/off . Am I off?
On the app. When internet goes down, you can directly connect to the PWs locally and still control through the appis that done via an App or on the PW itself?
