Customer photo review of NOVA 6548 | 6500 Watt (6.5kW) 48 Volt Off-Grid Hybrid Solar Inverter | Premium 6500W 48V Hybrid Inverter for Campers, Cabins, Tiny Homes, ADUs, RVs, Off-Grid | UL Certified

Excellent quality off grid inverter. Im a licensed electrician and have installed Growatt, EG4, MPP and now Rich Solar. Of all the inverters I've installed in off grid applications this is my favorite so far. I currently have 2 different generators, 2 is 1 and 1 is none. My big 240v 50a generator connects directly to my main panel, my small 120v 30a inverter type generator connects to this RS-H6548. The RS-H6548 output is 120v and connects to the primary side of a Victron 32a autotransformer, the secondary windings feed my main panel 240v split phase and lets us run a senville 18,000 btu aura heat pump. We are completely off grid, with that being said I trust this inverter to keep my family warm in below freezing temperatures. The plan going forward is to add an additional RS-H6548 and at least 60kwh of battery storage and 16kw of solar. Unfortunately I'm am going to have to save up as equipment of this quality is not cheap. Thank you Rich Solar for providing an excellent high quality off grid inverter. You've earned a lifelong customer from the quality of the product but also the customer support, I was highly impressed when yall called me back unexpectedly after I wasn't able to get thru to one of your support techs.

I installed the H6548 a year ago in my motorhome's storage compartment along with 3 Rich Solar Alpha 5 batteries and they have been working flawlessly ever since. (Disclaimer: I am an RV solar power systems design & install professional, however I purchased my own components from Rich Solar and was not given anything for free.) I installed the inverter horizontally and have had no overheating issues nor any mechanical issues due to travel. We also have been doing a lot of travel and the system has been in constant use. I was a little concerned about how it would do with the constant vibration from the road and also the smallish space I had available but no issues and we use it without babying it. I did add an EG4 Chargeverter to my system so I can use all 6500 watts when I want no matter what the shore power amperage is available. Hopefully they will eventually add a power boost feature like that found on more typical RV market aimed inverters. I highly recommend this unit and the batteries for those who really want to have a lot of power available and who want to go big on their roof solar. Great system!
