The vent is for the woodstove and it needs to be cleaned from the outside.
I don't think I could layout the 12 panels safely on one half of the roof only.
My intent was to keep a greater clearance by the roof eave.
Got it! My plan is to eventually get a Schneider Battery Monitor next spring when I will also add more battery capacity. Until then i'll be messing with the voltages.
I also hope to be able to eventually connect the EG4 to the Conext via BMS - just waiting for Signature Solar to get their shit...
Thank you both of you! I will check how to remove the breaker first then order the matching type. If different than in the link, I'll likely post it here again.
Cheers!
Moving the woodstove vent is out of question but I was able to move the panels around in addition to portrait layout.
Considering the cabin orientation (roof plane to mount panels facing East), what do you think about the revised layout?
Thank you for your royal authorization. I am glad you are allowing me to spend my money they way I choose to. I was waiting for you to authorize it before pulling the trigger and now I am ready.
Hi Harpo,
I am in a similar situation near PA and this past winter I decided to haul my EG4 battery back to my winter residence because I wasn't sure. So in summary, is it okay to leave these batteries in the cold weather when NOT in use (for storage purposes only)?
@Travis_signaturesolar
Thanks for the prompt reply. Right now I only see one battery (the existing one) under the "SEMB_BMS" device.
All (3) batteries are EG4 LifePower4 batteries. And they all have the same firmware update @JacksonSolar posted in the forums last year - if you search for his...
It looks like a busbar but from what I can see busbars are for connecting common wires together.
The connector I am looking for is not a busbar. If you see it in the picture I posted each connecting bolt is individual and does not bond to the next bolt.
Understood. So I am grounding the frames but my PV system is classified as ungrounded.
Got it, I need a 2-pole switch to properly isolate the system.
Thanks for clarifying it.
Jackson, that is great you were able to jump on this and possibly have the correct firmware file for the EG4 LP4 48V HW0207 batteries.
Could I just ask that you upload this file on Signature Solar website or have another one of your SignatureSolar colleagues confirm the authenticity of this...
Wait, what?!
I could have a 240V breaker inside my existing split phase panel? :oops::oops:
I'll try to post a photo of the panel, I believe it is standard US.
I can see how easily this prediction could turn into reality. A very slippery slope! I need to be careful here.
MPPT has (2) inputs, I think I will connect each array separately instead of combining them in a 6S2P configuration. I suspect this could help limit shadow issues with the parallel...
Ken,
Could you expand a bit on the relationship of my existing split-phase generator and the inverter type I should be considering in order to work properly with my generator?
I am a little lost on what specs the inverter needs to have because the generator is 240V service in split phase...
Here is goes @Markus_EG4 :
On the top end the batteries are not balanced with almost 300mV cell discrepancy, reducing drastically my overall battery capacity:
On the lower end, the batteries go from 40% SOC to 0% SOC + undervoltage alarm, shutting down my system. This is happening with a...
I don't know exactly why but the short answer is: the previous cabin owner built it like that.
I suspect he wanted space between the breakers? Maybe he was anal about the wiring spacing? I have no idea.
Thanks for the clarification. And good to know acceptable values are 10 to 15 mV.
I already reached out to the vendor, (SS) and I will follow up if the issue persists.
I have a 48V 8A charger that runs at 58.4V constant charging voltage. I do not have a 55V charger. Can I still make this...
Found this article explaining double x single pole breakers, but of course, they only show the wiring diagram for the 1-pole breaker!
https://www.cooltoday.com/blog/whats-the-difference-between-a-single-and-a-double-pole-breaker
I think I am getting the idea. I will need to get the panel...
I am back in the city now... we had no running water so we decided to come back to sort this out. I will have to finalize this once I am back in the cabin.
But I am confident on the pump replacement and in the 240V wiring. Ordering the pump now! I really appreciate the help!
My current off-grid setup has no grounding and I would like to address it but I am not sure what is the correct and/or best way for doing so.
The setup is the following:
- (1) 12kW Split Phase Generator located outside in a shed
- (1) 8kW Growatt AOI Split Phase inverter coupled to (1) EG4...
No MPPT at this time, only the Conext inverter and the standalone charger.
So change all charger settings to 54.85V and see how much charge goes in then increase charging voltage and so on?
Okay, I can try that.
So it sounds like I am still away from the target... dang it.
Yes, very clear.
Are you referring to a connector like this here:
They are still 30A.
Here is one possible ways I could wire a 4P in my situation, as I currently understand it:
Using a 4P Combiner Box
- run all (4) sets of PV wires on roof to Ironridge JBox,
- connect PV wire to THHN/THWN-2...
