For a system with one EG4 18KPV inverter, grid tied, 11 KW solar array, batteries primarily for backup, which would you pick for batteries:
A. Two EG4 PowerPro 14.3 KWH batteries, total 28.6 KWH for $7600.
B. Six Ruixu 5.12 KWH batteries with rack, total 30.7 KWH for $8300 (on sale for 10% off right now, $7470).
C. __________________________________________ (give me your advice)
Since this is a grid tie system, I need all solutions to meet code and pass inspection. I feel moderately secure with that for the EG4, but less so with the Ruixu. Anybody have insight into that? This would be in Florida if it matters. What UL certs do these batteries need to have?
I kind of like the Ruixu rack over the EG4 visually, will also take up less linear wall space. I also like the ability to change 1/6 of the energy out easily whereas removing the EG4 battery once it is stacked under the inverter is seemingly much harder and you lose 1/2 your energy if one goes down.
The EG4 wiring is kind of all figured out with the big junction box that sits on top of them. The wiring from the Ruixu cabinet to the inverter is not as preplanned and I'm not sure how that goes and what code requirements the battery leads have to meet. Do I need some sort of fusing or disconnect? The 18KPV has a battery breaker in it and the Ruixu will have BMS protection, so I am not certain.
I don't perceive any functional difference, I think they both will communicate with the 18KPV and perform the intended task. Is that correct?
