Hey my fellow diy'ers,
I'm currently in the process of Designing and building a portable solar generator. I'm going to be using brand new reclaimed 9s pouch cell packs.
Each pack is:
CAPACITY : 2890mah / 2.9Ah
NOMINAL VOLTAGE : 32.85V
FULLY CHARGED : 37.8V
FULLY DISCHARGED : 25.2V
Also each pack has its own BMS w/ balancing
*** not feasible to split packs up ***
My plan is you put 15 or 20 packs in parallel. Every 10 packs is just over 1kwh
So my question is:
* What type of inverter should I use? 36v or ???
* Should I use a large Buck or boost converter to change the voltage first?
* What size inverter do I realistically need in order to run a small flat screen TV, some fans, some low voltage LED lights etc... 600w, 1000w, 1500w etc...?
Initially I think I'm just going to use it without solar but want to implement solar charging in the near future. If that has to be taken into account when choosing an inverter. Most likely going to use 100w/150w solar panel...
Do they happen to make an AIO solar charge controller / inverter? Just curious...
I'm an electrician by trade and Electronic hobbiest / battery guy for 20+ years
FYI- doing this on a extreme budget!.!.! Looking to purchase a cheap / reliable inverter and eventually MPPT solar charge controller. My mother lives in Florida and doesn't have people to help her, and she doesn't like the idea of a generator so I figured this would be perfect for her.
