Just my luck! I ordered a 100W 20 ohm resistor before I learned about the extremely useful GUID in the resources about designing our own pre-charge inverter switch posted by one of the members here.
I now use the Wirewound Resistors 100 Watt 20 Ohm as a pre-charge resistor. Has anyone else ever used it? Is it working? Will it be enough to pre-charge the inverter without a spark?
I got Two 48v 200A batteries in parallel and Growatt SPF5000es. Any suggestions will be appreciated.
