I run a sustainable lifestyle center in Canada called Ketchum House. One year ago we upgraded to two Growatt SPF 3000TL LVM-ES (Dual phase) inverters and ran AGM batteries without issue.
Last Friday we upgraded to 4 Growatt ARK 2.5L-A1 batteries.
This is what works and doesn't work.
When we turn on the system, only running off the batteries, it works.
When there is input from solar or the generator after a certain amount of time, say, 5 minutes the voltage peaks and shuts down the inverters.
We tried setting the battery config in section 5 to LI but there is no indicator for the range to be entered in the "00" section. Because we are running 48V we set it to LI48. Just a guess -
With this setting it doesn't register the inverter and doesn't connect to solar. We receive two error or fault codes - “4” “20” [my birthday ]
So we set the battery config to USE with a voltage range of 47-57V.
This is what happens. We turn on the system and it runs perfectly on the batteries, no problem.
After turning on the DC fridge breaker after a short period of time the inverters shut down.
Leaving off the fridge and resetting the system, everything is running off the batteries fine and then we turn on the solar breakers.
The system starts to charge and the voltage increases slowly. After 5 minutes the voltage spikes to around 59V and the system shuts down. The top battery displays a red fault error code.
We replicate the same pattern without solar but using the generator and the same issue occurs.
The main issues are we cannot figure out the right programming to accept the new Lithium Ion batteries first.
Second when we program USE in section 5 we see a voltage spike that shuts down our system.
Any help will be greatly appreciated as I'm stuck Thanks Bill!
