Hello everybody,
I have a split-phase system with the following components:
- 2x Quattro 48/3000-35
- Smart Solar 150/70
- Cerbo GX (with internet access)
- Lynx Shunt, Lynx Power In, Lynx Distributor
- Battery: 1x BYD LVL 15.4
I installed/wired the system myself around 3 months ago, and as of now I've been using it exclusively to power a 240v well pump (3/4 times /month). It's been great, everything worked absolutely fine up until a couple of weeks ago.
I noticed that inverter L1 was making some "random" noises. This is what I mean:
- the noise is similar to the noise it makes while inverting (when the pump is on, but it would normally be both L1 and L2 making the same noise...)
- it comes and suddenly goes, even if there is absolutely no charge whatsoever (like an "interference")
- it happens while L2 is silent and cold
- when it makes the noise, L1 is warm to the touch, just like when it's inverting but it isn't
I tried to update the firmware on both inverters (it's 497 now) and re-configured the split phase through the Quick Config Tool, but the problem persists. Consider that I got absolutely no errors from the VRM, nor I was able to find any error inside the Remote Console.
Today I tried to run a small washing machine with just L1 (120v) and it went Overload and cut the power. I tried with L2, but L1 would still go Overload and cut the power automatically.
(I know I should use the Autotrasformer, but I was just making some tests)
This is what I see inside the Alarm Logs (VRM):
As of now, the system is idle, meaning that the battery is 100% full and there are no charges, and L1 is still making this noise (sometimes!). Wiring stops right after the two inverters, nothing is actually connected to them apart from a breaker which is turned off.
I don't understand what it could be, considering that the system is almost brand new and it's been working perfectly for the past months.
These are the settings for BOTH inverters:
Any help would be appreciated! I can definitely grant access to the VRM portal.
I hope I made a stupid mistake inside the configurations, otherwise I'd be worried.
Thank you!
