First timer here. I'm glad this conversation just started as I'm in the middle or researching and debating on what model inverter (5kW) to purchase. I don't need grid feed-in but I would very much like a grid assist feature to supplement the load. If I could start off batteryless, that would be a big money saver to allow me to build up a system over time. Short of a battery, I don't see how an inverter without grid assist would really work that well under varying load.
Can anyone verify that the PIP-5048MG will supplement the solar load with grid power? From all I've read, the PIP series are off-grid and will only do a hard transfer if supply is insufficient. I've sent this question to MPPSolar, but additional verification would be nice as some of the their responses I've seen are ambiguous.
