So at higher loads even w/out that little AC Unit, the problem would still crop up intermittently. Am I the only one who stares at SA screens for hours??
So I added a snubber filter to my large 250v AC unit across both poles. No change.
Last night I woke up a 2 AM and realized that this...
The Solar production curve went from this yesterday:
To this today:
So that one crappy little 400w air conditioner right next to the inverter must have put some serious noise into the system...
New info. I had a small (400w) air cond in my solor shed that was hooked up to Inverter 1, when on it kicks the usage up 400w. If I turn that OFF, my problem goes away. So I rerouted it to Inverter #3 where it cant hurt anything. Inverter #3 is only providing batter charging from some random...
This look exactly like what is happening with both my 2 split phase LV6548 inverters. I have 2 small AC units (1300w) and one larger 240v unit (2500w) that cause the problem when they are all on. And as the AC output degrades on the inverter that has the highest load (down 10v from the other)...
Yes. Look at the links, it's all completely documented.
If it doesn't work for any reason, I'll give you a full refund.
I have 2 eBay accounts, germanautopartsdirect and 911Porscheracer. Look at my feedback, over 1000 transactions and a perfect feedback score...
We can even use PayPal if...
Yup, I completely own that. I should have put a giant X on that data. Kinda hard to be a mind reader on a website... sometimes I run too fast without thinking.
Btw, from Pierre at SA
"Hi Jeff
We have an upcoming improvement to show the correct output frequency and voltage instead of averaging it. Unfortunately the load percentage will still show an average across all inverters.
Kind regards
Pierre - SolarAssistant"
I actually never said it doesn't...
All due respect... I have disconnected inverter 3. It makes no difference. As acknowledged by Pierre, SA doesn't know how to correctly handle (report totals correctly) a standby inverter acting only as a charger. And I have measured both the AC AND the DC voltages, when the problem appears...
THAT oddity is our lovely Solar Assistant averaging my THREE inverters. It has ZERO bearing on reality- I've reported it to Pierre at SA so he can find a solution. As I said, inverter #3 is for battery charging ONLY. I have it added to SA just so i can see how much power is being generated...
yes both are set to SBU and have always been. "timers are not set" - do you mean the power settings?.
This happens in the middle of the day when the battery is at 100%. Battery current when it happens is 0... The grid shouldn't be involved at all at this point. Any power being sucked...
I have something strange thing happening w/ my LV6548s operating in SPLIT PHASE.
Any time the load on one of the inverters goes above about 60%( which, coincidentally exceeds the available PV power), the PV power on that inverter drops to almost nothing and the grid kicks in on that inverter. I...
Im seeing something strange in the battery current the values reported by SA.
I have 4 batteries, and I've verified that each of the battery_x_current numbers are correct adding them together equals what my shunt measures....
What are "sensor.battery_current" and...
Smal draw (5V 1A Power Supplies power them via USB-C), and yes, you can program everything about sleeping. I have an existing motion sensor in my kitchen, so when I move the display wakes up via a HA Automation. There are also extra pins on the ESP in the display that can be repurposed to hook...
