Anyone know the max charge/discharge rate is on the Dyness 5kWh battery?
50A recommended, 75A max on the newer BX51100 models.
This is for the B51100 modules I got:
Dyness themselves said to not go over 50a per battery and when you select Dyness LV as the battery (on the solis) it just adds 50a per battery as the BMS sends over anyway.
Yeah with one 5Kw battery all I ever get in is 2.5Kw (and out) . Would be nice to have double that sometimes but I guess I need a second to achieve that.
slightly ashamed to ask this very basic question - but i know u good people will be kind.
I got an Eddi added to my system today (delighted with this - not sure why i left it out to begin with).
I have been using the Solis Apps and Cloud all along - and im happy with the monitoring of that. Am i right in thinking i CANNOT view the Eddi in Solis at all? I must invest in the MyEnergi hub - and abandon the SOlis CLoud (or duplicate it)...
Or is there any way to view the Eddi either combined in Solis CLoud or at least online as SPOG?
Unfortunately not. Unless you roll your own solution using HomeAssistant or similar, but that will still require the MyEnergi hub.. perhaps a Shelly 3EM might do what you want? One CT on generation, one on grid, one on immersion/Eddi?
nah its grand. happy enough without it, i saw the anntennae and was wonderning - but the RTFM seems clear - pay extra for more options like the hub etc. once im keeping my diver to grid number down im happy out.
If its a fairly new Eddi are you sure its not got the inbuilt hub? They updated both Eddi and Zappi to have an inbuilt hub also allows the two to communicate via wifi/ethernet instead of radio communication protocol they used to use
Doesnt seem to according to the manual. model is eddi-16a1p01. Its newly installed but the supplier might have had it in stock a while i dunno.
Got panels installed almost 2 weeks ago. It rained for first time on Friday night and the RCD tripped. Was suspicious about solar panels and when googled came across a UK thread where similar happened. Anyone else encounter this?
Was it definitely the RCD as opposed to the solar MCB?
Yeah the general RCD. There is a separate box the solar panel guys put next to fuse box. Not sure what's in there
Leakage current issues can be hard to diagnose. Definitely a task for your installer.
A reminder, anyone with Electric Ireland to submit their readings today to avoid paying the 25% increase later in the month on them
For newbies to solar, post your monthly stats or check if your system is performing in line with others with similarly sized systems.
It's rained on an off all weekend and RCD only tripped that one time. Maybe it was a coincidence? Should we wait and see if happens again before contacting installer .
Rcd tripping is hard to pin down.
Usually the solar has its own rcbo(rcd and mcb combined) now so should be unrelated to it.
Is there outside lights or something along them lines on that rcd? That and rain usually go together.
Older rcds tend to develop a "hair trigger" too and trip sooner than they should.
I'll check with installer, likely has seperate RCD as theres a new box next to fuse box. No outside lights or anything like that .Even if does happen in future and caused by solar panels, there's no risk etc other than inconvenience of resetting rcd? Yeah it's an old RCD
Replace the RCD, they can go unreliable over time. Not that expensive, electrical wholesalers.
My RCBO has been tripping constantly until I started isolating the panels before I flicked it back on. Was told to disconnect the earth at the panels and since then has been hell of a lot better. Trips maybe every month or 2 now. Next is to upgrade RCBO to Garo see will it fix it completely.
Yeah, they are quite sensitive to any earth leakage. Not sure that disconnecting earth at the panels is "code" though :-) Sure, it's not as if people are up and walking about on your roof regularly, but if an issue was to occur...
My inverter's RCBO trips whenever there are sustained high winds. Probably happened 2 or 3 times over the last year. I live in a rural area with above ground ESB cables. Told it happens to others in similar installations.
Ha, they are ground mounted...
Ya see the high winds probably create static over the panels which is picked up by the earthed frames, just a guess..
Been awhile since I did electrotechnology (30+ years!!), but wondering if high winds would swing the wires and change the impedance on the cables due to the differences in distance of live & neutral. Just throwing it out there.
Sam, ground mounted. Yeah, it's probably ok. Dunno. Just wouldn't like to see you get a ZAP. It's odd that the problem went away when you decoupled the earth, that would suggest that you have some leakage. Could it be the case of coincidence over correlation?
Grid over voltage alarm today!
house is not pulling from the grid despite there being enough PV….
anything to be concerned about?
How high? First time? I get them when exporting >5kW occasionally. Nothing can be done about it (except limiting export lower), I have an 8V drop from my inverters 60m away from the house so if the grid is running high 240s, my inverters have to break 253 where they would just tick out themselves. Voltage in the house never goes above 253 when measured at the socket so I'm not worried. You should plot your voltage at multiple points in the house when you're feeding in. If it's happening when you're not feeding in might be worth getting the ESB out to install a logger.
See blue for inverter and yellow for house here today:
Wouldn't be too worried about the grid pulling unless it's sustained, could just be slow update rate on the inverter's display.
Where are you based Andy?
I had OverVoltage alarm today also, looks like the same time as you. North Co. Dublin. System was in Alarm state (no solar/battery output) until approx 10/15 mins after the voltage dropped.
This graph is the voltage on a WiFi socket in the house. (I didn't have a HA sensor setup for inverter voltages before this, but confirmed that is was the same as the below is showing)
Yep, North county Dublin!!
and seemed to resolve itself at about ~6pm..
I have had similar. Seems to be common enough in google searches. Manufacturers recommendation is actually a 100mA trip on mine Mine tripped most often in October/nov and Feb/mar when combination of wind and rain. Had a garo rcbo and over time it did get more and more sensitive. Replaced with a Hager and find it much better. Have only had 1 trip in 5 months during one of the storms and the inverter alarmed at the same time for a mains over voltage so maybe that tripped it
