Update, whizbandit whom either works for midnite or beta tests for midnite or both (I don’t want to assume incorrectly) had the following information in response
“I was the original tester of the SRNE 3548 3500W AIO (All In One) inverter with 140VDC MPPT input. I tested it for about 3 years here at my homestead in Florida, through 95 plus degrees heat in the back of my garage, through a dozen tropical storms and hurricanes. I had my whole house's 15 amp circuits on it, lights, ceiling fans, 15A outlets, cable box. It never missed a beat, never crashed or shutdown during outages. All the heavy circuits were on a stacked pair of old Trace SW5548's which also working flawlessly. I have 2 central A/C systems, a 2 ton upstairs and a 3 ton downstairs. The 2 ton was the only A/C on the battery and it was on the Trace setup.
The SRNE 3548 shutdown with a fan fail alarm about 2 years ago and I bypassed it & jumped the circuits over to the Trace system where it stayed until last year when I got a SRNE 10K 120/240 unit to test. I moved the circuits back and also included the 3 ton A/C just for a real test.
The 10K SRNE started and ran my 3 ton A/C along with all the 15A circuits that were once powered by the SRNE 3548. It's been running for almost a year now without a glitch. Midnite will probably not be re-branding the 10K units yet, at least not until a warranty department can be setup and we can deal with the failures in-house.
The biggest issue with the SRNE re-branded to MNS DIY is Midnite did not do enough forward thinking for warranty & support. There was/is no DIY series repair bench setup, warranty was handled by shipping a new unit and piling up the bad units. I had a lot of them shipping to my shop to inspect, very few suffered failures from manufacturing, most of them were abused by the DIY customer crowd not understanding how to properly size, wire and setup a solar power system. They would just put a small battery and/or too small battery cables on the DIY3048 or DIY5048 and the strain would blow out the inverter's DC to DC section and throw a Fault-5 (DC to DC fail). The DIY 3024's seem to suffer from a few cooling fan fail issues, not with the fans but with the internal fan sensor circuit which no one knows how to repair as we don't have schematics. Plus, the labor to disassemble and reassemble is massive, it takes 45+ minutes to take a DIY3024 apart, if it's not burned then another 30+ minutes to locate bad parts and another 45 to 60 minutes to reassemble & test. Really not worth repairing...”
Seems like some pretty useful information. Shame that the 10k won’t be offered under the midnite label, but hearing his feedback on them makes me almost want to stack 2 of the 5kw units for split phase
