Hi Guys, I have a Growatt SPF5000TL. Working fine but when I try and input from a 40 year old 3.75kw generator, it aknowledges a utility but doesn’t take any input. If I plug in a later genny, Obviously pure sine, it works. Is the issue that the old genny from the ‘80’s isn’t putting out a pure...

Hi Guys, Im trying to fit a breaker between the controller and panels at the controller. Regardless which I use, the resistance is great. The controller will not recognise the voltage. If I bypass, the controller recognises the solar. Ive tried two breakers and two isolators. Cheers guys.

G’day all, I have the SPF5000TL hooked up ATM, but what I’m wanting to do is add another unit for more panels. Now I dont need the inverter that the SPF5000 has so I was considering the SC48120 which is a controller only. Now it doesnt have the communication means to hook up to the SPF but when...

Hi Guys, Epever 5415AN has in its specs ‘rated charge power’ and ‘max pv power’. Not quite sure what the difference is. Is it stating that up to 2500w at 48v is the requirement and anything above put into it up to 3750w will be discarded? I’m assuming I need to set up my strings/parallels to...

Hi Guys, I have 24 X 170ah SLA batteries. ATM all i am running is two fridges and one freezer. During the afternoon all batteries are fully charged. Within 3 1/2-4 hours (no sunshine), the batteries are reading 12.25 volts. Now this is under a little load. Switch off inverter and they will read...

UH OH! Looks like I may have cooked the charge side of my controller/inverter. The inverter works but not the solar controller. I have 12 x 250W 38VOC 8.3A panels on the roof. I have had the system working fine with just one series string of 4. Yesdy I tried to connect up all three strings of 4...

G’day all, I have 24 X 170ah 12V SLA storage batteries I want to set up as a 48V battery. The solar controller has an inbuilt inverter. My concern is the inverter will draw on one series of 4 batteries without the others balancing over quick enough to keep the DOD equal across all batteries. Is...

G’day guys, I have 12 x Enersys Supersafe 12V 170ah batteries 12T170FS manufactured in 2018. They are a standby/backup battery. How do these fair in a battery bank for solar? My intention is to double up on these to reduce the DOD. Have these batteries been successful in an off grid system...

G’day all, I have in my caravan a 190ah Supersafe by Enersys SBS 190F deep cycle. It’s permanently connected to the solar panel. Should I disconnect it and give it a tweak every so often or is it ok to be connected permanently with the MPPT? Cheers all. Al.
