Hey all,
So I've had my system up and running since about February of 2024. Currently, I have two SGP 48v 6000w hybrid inverters in parallel (TP6048). They are connected to my solar panels, each as 10 in series-parallel 5x2 sunpower 330w ( for a total of 20 panels.) I also have three batteries from SGP 100ah 48v LiFePo4 connected in series. I also have the grid-connected via the main panel. Thus far it has worked in ebs and flows of minor problems here and there with periods of it working perfectly.
Heres my questions/problems. Any help on any of these is greatly appreciated.
* NOTE: yes i have tried contacting the manufacturer and their advice is garbage at best. Not to mention they are only awake when my side of the world is asleep.
1. When its working "properly," as soon as the batteries are full, the power in the house shuts of for 2 seconds then restarts. It happens daily almost like clockwork just depending on what time of day the batteries get full. (Any advice on this or why its happening?) We've lived with it for the past 7 months but it's rather annoying resetting all the clocks.
2. Most recently, the batteries discharged to what I believe is too low of a voltage and now they wont charge, which is setting a whole string of error codes off. Most of which can be reset or fixed by putting it in grid+solar mode. I think they are stuck in a protection mode but I can't seem to figure out how to get them out. This isn't the first time this has happened and I pressed enough buttons and changed enough settings and all of a sudden it started working again. Would love a fix for this?
3. Going off the last problem, my battery settings must be all out of wack. Everything is in numbers as far as things like, battery cut of voltage, bulk voltage, float voltage, max charging current, ac charging current, back to grid voltage and discharge voltage. Any advice on what these should be set at would be greatly appreciated.
Here are some answers to common questions ive been asked by SGP.
Yes the inverters are in parallel.
When its working, i have it set so that it goes Solar, battery, grid as far as power source priority. I have it set for solar only, to charge the batteries. I have the I have the solar priority to charge the batteries first, then load, then return to grid. (I don't return power to the grid because this isn't an approved solar setup up)
Any help is appreciated. I can answer any questions as well. Ive been searching for similar issues but they seem to be close, just not close enough. Thanks for the help and support in advance guys!
