Solar Wizard
Well let me tell you my experience.
I started with solar to mainly run my HVAC to offset the cost here in hot and sunny Florida. Started with Growatt 6000T that worked quite well but it occasionally (maybe once per month) could not start my year old Carrier regular heat pump system. It would seem to lock up and the inverter would shutdown from overload. I would connect the compressor back to mains to kick it.
When it was time to upgrade and expand the system, I ordered a pair of SP6548 and literally the next day found an ad for 45 panels, 4 batteries and a Solark 12k. I removed them all from the house (it was being sold) and decided to use it all instead. Well the poor Solark absolutely hated the compressor and couldn't start it several times a week.
So I decided to try the SP6548 pair. They handled the compressor fine with no failed starts. I did see a couple of times where the inverters showed over 80A and one time I heard quite the snarl from them. They have been running fine for several months and I decided to go 100% off grid, so they got the dryer and water heater added to them that could pull 12kw of their 13kw output. Again they handled it fine, even starting the compressor with the dryer or HWT running. The Solark is running the rest of the house and charging my 6 batteries from around 8kw of panels.
Welp, last night after running for a month, suddenly everything went dark... BOLLOCKS.
Headed out to the garage and it was terribly quiet and dark ?. I measured 52.x V on the easiest battery to get to, but noticed all 6 circuit breakers on the batteries had tripped WTF.
I clicked all the load AC breakers off and hit one of the battery breakers, inverters started to light up and all seemed ok. Flicked on the Solark loads and all was well and I had lights again. Turned on the other batteries and all good, so I hit the other AC load breakers and when I hit the SP6548 output breaker there was a bang and it all went dark again. Mrs QH decided to leave me to it lol.
I wasn't about to fuck around any more so just got the Solark running the house for the night and assumed the SP pair had taken a dump.
This morning I checked everything over and tried again, bang went the HVAC breakers when I tried it. Bugger, compressor dead ? Connected it to mains and it snarled like the devil but started. Sounded fine. Connected it back to the SP pair and everything was fine back to normal. I checked the logs and saw a gianormus spike right when the compressor was trying to start last night. Over 150A AC and over 600A from the batteries was logged before they cut off, I have 1300A worth of batteries and the SP6548 pair survived the hammering they got.
So that is my experience with them so far.....it took me the whole first half of a boring game the Yanks call football to type this on my phone lol. Happy Superbowl all.
