Anker E10 Help - Solar Array Sizing
Hello. I am looking to get a full E10 setup for whole home backup and being able to take advantage of lowered electric bills via TOU. My configured system right now is 2x Power Module with 4 batteries and the Power Dock. I may or may not get get the Smart Generator 5500 for piece of mind in an emergency situation. With all of this said, I am thinking about the right solar panel system for this setup.
I live in a community that will not allow ground based solar panels, so my option is limited to fixed roof panels. My goal with the solar panels is solar energy is keeping the batteries charged up as much as possible, and the home is powered via the E10 system as much as possible.
I do see Anker has their own 440w panels, but my research shows it would be difficult to impossible to find somebody to install them on my roof (this is NOT a project I am interested in doing in any way, shape, or form). Too much risk/unknown and the chance something goes wrong with other parts of the system - As a professional myself I totally get why many people would never touch a job like this.
With the above in mind, I am thinking the best path is to evaluate solar panel providers to quote out a roof solar panel array, and link them into my E10 system.
My question is what is a good solar array size for this E10 system? Just using Google/Gemini it's saying a 4.2 to 4.4 kwh system would take ~3 hours to charge up each Power Module/Batteries, and that's at full sun. I believe I could go up to around ~9 kwh in terms of panel capacity as that would be close to the max solar input.
I am in the Midwest so can't necessarily rely on "full sun" all the time so the penchant is to size high. Again, not a crisis if the solar is not ALWAYS keeping the system charged up but I am wondering if anybody that is more versed in these systems (i.e., anybody but me!!) has some thoughts on a good solar array size and what the ballpark price estimate would be for such a system?
Many Thanks!
