Most residential services are billed in KWH instead of KVAR. I hope you are not in a KVAR billing area. That could make running rpc's expensive. The term might be KVA.

It could make it worthwhile to go through the proper tuning of the RPC -- first to make the converison more efficient, and then to make the power factor optimum -- easy to do with AC rated capacitors, a clamp-on ammeter and a bit of time. It will also make it less likely to trip circuit breakers. The term might be KVA. Too late to google, I'm up 4 hours past beddybye. Night. You all be safe. KVA is the measurement unit. KVAR appears to be a brand of auto-tuning to optimize power factor/. KVA billing seems to be used mostly for industrial power users -- which encourages them to tune to opimize power factor.
