Hello julle, typically thrown away, but would be worth gold to me.
Office type UPS 5 to 10 kW 230VAC but 180 V nominal DC which used 16 x 12V LA battery banks.
(Not economical to replace)
I built a solid 200V 10 kWh Lithium battery but the Eaton 9PX 5kW UPS has now retired.
A 10kW UPS was given away here but I was too late to dibs. (wonder if that UPS is even in use now…)
Willing to pay copper value+. Bought an Eaton 15kW UPS but that runs on 400V DC.
Before reconfiguring my powerwall, thought of asking around for a direct replacement.
Centurion area, but will collect anywhere in Gauteng.
