Hi guys (and ladies :heart
I'm looking to build a wall for my soon to beconverted van (kind of RV) to support a fridge (12, water pump and my electronics like smartphone, laptopand projector.
Most RV enthusiasts will have AGM batteries/lead acid combo but i would like to try my luck having a powerwall as any "normal" house would have.
The battery bank willhave 3 sources for charging being from the most desirable to the least: solar, van alternator and mains when available.
Current parts wish list:
- Solar panel:GWL/Power Solar panel GWL/Sunny Mono 300Wp 32V
- Pure sine inverter: there's a choice between12/24/48V/120V and 1000w 1500w 2000w 2500w 3000w to run my electronics
-CTEK D250S Dual: it's dual purpose, it's a MPPT controller and is also a automaticcommuter from alternatorcharging to solar charging
-CTEK SMARTPASS: will allow charging up to400Ah
- Mains charger for when i have access to 220v AC: did not find the best option yet to charge 18650 battery bank
Project goals/considerations:
- power the fridge 24/7
- easy to build as my knowledge is limited
- all i have a soldering station
- do it low cost - getting used laptop batteries to get cells from (already have some at disposal)
- safe to use: i will put the battery bank in a safe vented enclosure but it will still be inside the van where i will be sleeping
- up-gradable: i would like to be able to size it further by adding banks whenever i get enough cells to build more. therefore, i would like to build it in a way that the system is already ready to accept more capacity
What are you toughts on this? should i go for it or should i just stick to the mainstream acid batteries for this purpose?
Keep those ideas coming!
Thanks!
