DIY Solar Inverter / Charger / Backup system

[samueldaniel7]

So need some help / advise,

Got this UPS from an auction , 5KVA , 192V Battery system voltage came with 8Kw battery packs (still dint check the state of health)

https://www.apc.com/my/en/product/SRT5KRMXLI/apc-smartups-srt-5000va-rm-230v/

so i want to charge using solar panels during day time, (and consume it as well ) and charge during night 10.30 - 5.30am its cheap ne

my problem is can we buy a MPPT or PWM charge controller for 192 V , or we need to make one

Average consumption during day time is like 500watts , so if i fix like 4 - 6 panels its sufficient ne

192V isn’t pretty common. Finding BMS or charger controllers will not be easy. If you have more spare time it will be good project.
However you can proceeding with like this one
