Hi, after my sma inverter went pop on me I have picked up a Growatt 3600MTL This is a good thing as I already run Growatt sp2000 and have shine link and spare dongles. I have it all working but every night when the DC shuts down the inverter switches off as does the dongle. Then when sun up...

Hi, I have posted this before but had no answers I have a Dafron GBLI 5001 The BMS is dead as is the controller but the battery pack is still good. I want to add a Growatt spa3000 after my inverter to catch and store any energy I’m send ing back to the grid. I would rather I have it than the...

Hi, after trying to repair a growatt system and failing I have switched over to a SOFAR HYD5000 hybrid inverter / charger. I have set up and been watching the system on the Solarman app and its not running how I would expect it to. I would have guessed the house has priority and any surplus...

I think it’s time to replace my faulty Growatt SP2000 charge controller. I’ve been having lots of trouble with it recently. But which route do I take for the future. Stick with Growatt and go to maybe an SP3000 or SPA3000 as I already have Growatt monitoring via a shine link and also a...

Hi all As above really. I am trying to bring back to life a dafron gbli5001 from my Growatt rig. I bought the seplos 3.0 from Frogstar but the loom and instructions show it’s connected to 16 cells. And the dafron has 14. Any one know a work around / setting that can be changed. And how to...

Hello to the great hive mind. I have a question about the combination of a lithium Daron battery pack and lead acid batteries to run in parallel together. So this is my set up, I have a Sofar HYD-5000es hybrid inverter and a 5kw Dafron Lithium Battery pack but it needs a new BMS, My plan is to...

Hi all I have a growatt SP2000 solar battery storage system which uses a Dafron 5kw battery pack. The system has been in a dry clean storage unit while I was moving house, and over the weekend I have been setting the system back up. When I connected the SP2000 controller to the battery it is...

Hi all My SHUCO SMA 1700 decided to poo its pants last weekend with a loud bang when connecting to the grid. It has taken out one of 4 transistors along the back of the PCB that attach to the heat sink behind the 4 capacitors. Not being shy to open it up at work on my work bench. And a hive...

I have surplus from work lots of 12v 38Ah fire alarm batteries (16 at the moment) I am planning to run them in banks of 4 to make a 50v system and then combine all 4 banks (with over current protection) to make a large 152Ah storage bank and run a Charge controller such as growatt or solax. I...

Hi. I have just swapped over from Growatt to SOFAR. A hybrid inverter / charger 5kw Hyd-5000es I believe. My old sp2000 system was flawless but the new SOFAR is playing up. If there is anyone out there clued up on SOFAR commissioning I can run through the set up as it’s not charging and...

Hi All. I have just replaced a faulty Growatt sp1000 with a used SOFAR hyd5000es I am running 200ah of lead acid but the inverter/ controller which ever you call it isn’t behaving the same way the Growatt did. Growatt-charge batteries with excess solar before sending back to the grid =...
