Thanks very much! I need to look into assembling the 3.2v 280ah cells. I just learned about those. I like bulding things and I definitely like saving money so I'm going to have to do a deep dive into them on Saturday.
As for location, I'd try to fit as many as possible on top of the cabin. I...
The largest individual item is a microwave at 1470 watts AC, but would only run 30 minutes a day.
The mini-split Air Conditioner would run at 1060 watts AC for 10 hours a day in the summer, making it by far my largest consumer.
I'd like to keep it under 20k but I know that's stretching it. My envelope math is looking more like 22-25k. I could go over if I save a little more. I just learned about building the 3.2v 280ah blue cells so I need to look into that and see if building them would be a big savings.
I'd rather...
I'm in the US and would like to use solar even if the grid goes down while using a grid-tied system.
I'd like to get the cost savings of feeding the grid while the grid is up, but if the grid goes down I want to be able to use the solar to charge my batteries. I'm not concerned about a failover...
Thanks! I'm new to this too and it's good to find out that other people have thought of this and have solutions. Sol-Ark seems like a good company and they have good reviews so I'll keep them in mind. The switch is clever as well.
Hi - I'm trying to plan an off-grid system and have run into a problem with selecting an inverter/charger.
The system needs to handle 22 kWh per day (most days won't need that, but just being safe). I plan on using 48v for everything, with LiFePO4 batteries.
Based on that usage, this site...
Hi robby. The conversions of parallel vs series always get me. I need to really read up on that.
So you're saying the Quattro 48/10000 charger inverter can handle all 24 panels if I connect them the way you described?
Also to clarify: as far as watt usage at any moment, I don't expect it to...
I thought the Quattro is an MPPT charger combined with an inverter. Is that right?
Also, I don't expect to ever draw more than 4500 watts from an inverter at any given moment (and that much would be rare, but still possible). I should have mentioned that in my first post.
I'm planning on powering a cabin off-grid. None of this exists yet (not even the cabin or the land for the cabin) but I don't want to buy anything until I am sure of all details.
Thanks! That helped. I just picked Victron as an example. I don't have any equipment yet and am just planning. I just know Victron has a good reputation but they're pricey. Pricey is ok because I want to avoid "cheap" items, but of course I'd like to save as much money as possible since this...
Thanks! For batteries, the same calculator suggested 34447 watt-hours (718 amp-hours @ 48V), LiFePO4. My envelope math was similar.
As far as the all-in-one, I'm totally flexible at this point since I have no equipment and am just planning. If I can do something better and/or less expensive but...
