Howdy Community…..
Can you please help…..I am trying to find the size (capacity) of the capacitor bank in the Quattro 48v/10,000 kVA inverters…. so that I can calculate the correct Ohms of the resistor I need to install in a pre-charging circuit. I have multiple systems with 2 and 4 Quattros in parallel, with up to 30 or 36 Pytes batteries. But they are earlier battery models with no pre-charging capability. So, I am retro-fitting pre-charging circuits to protect the inverters and the batteries.
Thank you for your assistance.
Cheers,
Jim
The Quatro has a built in precharge mechanism: This is done through the remote voltage sensing terminals. If these are wired to the battery bus through a 2 pole 2A breaker, then closing this connection first will precharge the main capacitors.
