Would appreciate this group's help to review the plans for my very first build. I was inspired by Will's videos and the comments from this forum and decided to go for a DIY 24V AIO solar system rather than just buying the Ecoflow Delta 2 Maxes (or equivalent). I have been impressed by all the great advice, sharing of trials & tribulations, and support that this community has given to the craft of solar systems. I didn't realize how accessible it could be until I came across this gold mine of information!
Inspiration / goal:
Comparable cost for Ecoflow D2M + D2M EB: $3,200 MSRP ($2,548 on sale)
Feel free to throw any questions, suggestions, comments my way!
Thank you!
Inspiration / goal:
- Build my own version of Ecoflow's Delta 2 Max w/ D2M Extra Battery (but cheaper, can be upgraded & repaired!)
- Standalone energy storage solution that has the potential to qualify for the federal credit (pending IRS publishing actual details) - sized the system at least 3kWh
- The minimum sizing of the system should be able to sustain a full size refrigerator (avg ~150W) in the event of a power outage, i.e. ~3.6kWh per day.
- Just "portable" enough so that I can either move it around the house or eventually put it into a non-existant camper van in the hopefully near future.
- Leverage the energy storage system to store any "excess" solar generation that my existing grid-fed system generates today. We generate an excess of about 40 to 80 kWh per month during the summer months. (We are on net-metering so the actual "savings" from this will be relatively minimal so this is more "because I can".
- MPP Solar LV2424-MSD 24V system (decided to go for 24V instead of the EG4 48V for my first build - due to weight, size, cost & safety)
- 2x Power Queen 12V 190aH w/ 150A BMS - total capacity 4,864 Wh
- 4x 170W Alrska solar panels (Got them for ~$0.67 per Watt so decided to give them a chance even though I can't find much info about the company or their panels. I really like the size and look of the Shingle tech cells - similar to Ecoflow's panels. Couldn't find similar ones from Renogy, Rich Solar, or HQST. Most importantly, they operate at 8.83a. I have a long run so trying to keep my voltage drop to a minimum.)
- 2x Power Queen 12V 190Ah total capacity = 4,864 Wh
- Cost per Wh = $0.35
Comparable cost for Ecoflow D2M + D2M EB: $3,200 MSRP ($2,548 on sale)
- D2M + D2M EB total capacity = 4,048 Wh
- Cost per Wh = $0.79 MSRP ($0.63 on sale)
