Only one year experience so far with some ~29m/s (65MPH) direct hit winds so it's far too early to say how good or bad my setup is. CCA treated poles were "free" and still got plenty of them. No problems so far though. It's a big sail. 2,9m x 4m, so over 11m2 while reaching 5m from the ground.

I understand people being excited about auroras but for me they are mainly Meh as we see them all the time here. Also day is almost 17,5 hours long now so only few hours dark enough to see anything. Heard they were nice but was sleeping. Hopefully I can finally turn heating off tomorrow. It...

Maybe THIS THREAD will give you new ideas.

Sorry for that. 🤣

Go to Aliexpress and search "4p 125a ATS" and you get loads to choose from.

It's always good to focus $/W. Nothing wrong there. Just keep in mind that white shiny TPO is perfect for bifacials and they can give you something like +15% to +30% additional power compared to monopanels depending installation. It's all about getting reflected light to backside of bipanels so...

Not RV, but I'm using these in my system although 4pole 125A 400V (3-phase AC here). I have two connecting/disconnecting AC coupling to my inverters and one to switch island mode in my main panel in case of outage. Very chinese but with all important CE-marking and seem to work so far. No sparks...

Or $600 worth of aluminum. At least in here.

So you don't plan separate garage/tool shed? Everything is incorporated in one building? That's ok and underground concrete vault would do with fire stop and venting outside like @Hedges already said. Also keep in mind that there's a lot of heat produced (inverters, not so much LFP) and climate...

No. Unfortunately it is not.:cry: But then maybe you don't have -40C/-40F... Strongly suggest separate building with climate control for your solar stuff/batteries. LFP chemistry is considered safe, but I wouldn't want to sit on that much power.

PV is so cheap and getting cheaper every day so oversize batteries AND PV if no generator.

19 years and counting. Got my 48V 625Ah(C/5)/749Ah(C/20) Exide Tudor FLA forklift battery for free over a year ago. It was used on forklift but eventually rejected as it got too weak. It was unused almost a year before I got it. Got it up to 90%SOH but disconnected it from my system for last...

I do own Fiskars CEO's old official car, a 1956 Dodge Coronet. I got it museum approved over 30 years ago and it has been about 25 years since last time I have driven it. It's in excellent shape still almost like the one in picture below, but needs a thorough cleaning because of thick dust...

Can't see how this is even possible. Both Deyes making little over 8,5kW PV so combined ~17kW but still charging 7,13kW + 12,93kW = ~20kW to my batteries. Work mode is Zero Export to CT on both and no grid charge allowed. I have no shunt on my batts as Deye has some internal way to calculate...

Sol-Ark 60K is hybrid. OP might not need battery charge. Deye (=Sol-Ark manufacturer) makes GTI string inverters more than twice that size. Still ~180 string inverters vs 50 bigger string inverters (=central).

No net metering as we have spot prices here. One can choose to buy with spot or fixed prices but selling uses always spot. I have fixed price which is ~12c/kWh all included this year. For next year I need to make a new deal. Just as I'm typing this my system is backfeeding ~40kW as spot price is...

Are those trees on your property? Burn them all!!!🔥🔥🔥

My array has 135 azimuth so in mornings it works really nice. It's the afternoon around 15.30-18.30 when there's a huge dip in production due to sun angle (see post #187). This is why I'm going to install 15,4kWp monopanels on nearby shed roof with 235 azimuth. Hopefully it'll help with...

As I DIYed everything my cost with GTIs (4x Bluesun15K) only and no battery would have been ~0,85e/W. This was my initial plan. ROI maybe 3-5 years? Then I got a 30kWh (C/5 rating) lead acid battery and 7,2kWh UPS for free and found unused 3kWh UPS for 600e and decided to sell two GTIs and get...

Even while other string is totally shaded and other one is having full sun? Would be fun to test without and with diodes though as I understood those 3-way splitters are cheap.

Got Deye12K to my FIL and he is going to connect 6,6kWp to MPPT1 and his old 3kWp array to MPPT2. Now he wants to add more panels to MPPT2 with 180 degree difference in azimuth (adjacent slope in his roof) by paralleling strings and wants to use 3-way split with MC4 connectors including diodes...

270kWh today. Almost perfect day. Backside production at 21.00. Also witnessed 5,5kW power transfer between Deyes through LOAD-ports (Deyes not AC-coupled with GTIs, but GTIs pushing power to my loads/grid so keep an eye left side of the screen only). Upper one delivering power to lower one...

Monthly productions and PVWatts predictions are all mentioned in this thread. If you want to find Dec-23 production just look for few first posts in Jan-24. Nov-Dec-Jan is so bad here that doubling my PV to 88kWp would do almost nothing meaningful productionwise especially compared to my usage...

Not much to compare with, but yearly target was 40MWh, PVWatts predicted 42MWh for my setup and 44,6MWh came true. It seems to work really nicely with snow (even blizzards) and fog. There's a study saying that due to snow covered panels here in Finland almost half the amount of summer production...

OK. I think there are many Seplos V2/Deye/Sunsynk users here so hopefully OP can get this sorted out. @~3,16V cell voltage he has still some safely usable capacity left in his batts. @houseofancients are you running closed loop? If so how low does your cell voltages go?

I see your problem there in the picture. A very different looking BMS tool compared to mine (got it from the manufacturer, but don't know even know who's the manufacturer of my BMSs as my batts are prebuilts and very cheap ones, so they probably have cheap/shitty BMSs too). Maybe your problem...

Yes, but it's Chinese engineering... :unsure: (actually they have been very helpful every time I have asked help) With SOC protection enabled my batts stopped discharging around 3,17-3,19V cell voltages. From all the reading I have done I concluded going down to 3,0V and with max 0,16C...

Well... You can get bifacials to work even roof installed, but you need to get that light under those panels. Actually I'm sure 20-25% gain can be achieved this way at first but probably fainting to 10-15% over time.

I did this too. There was nothing to trigger charging no matter how hard I tried to find it. Then went through "protection list" and disabled "SOC protection" for the heck of it and got it working.

Yes, but only after disabling "SOC protection" not "SOC warning" from battery BMS. And mine will charge from the grid regardless Deye settings. I have closed loop connection, so it's the batt BMS who is in charge. Normally it won't charge from grid if grid charge is disabled from Deye and...

EXW and never again.

It doesn't matter if your panel is vertically or horizontally installed. It's all about getting light to the backside of the panels. The more light there is the more chances it has to hit the backside of your panel (reflecting from the ground, nearby buildings, trees, fences...). Albedo plays a...

Yes. :) Bifaciality factor of 80+-5% means that if front side is capable of making 600W, then backside is capable of 80+-5% of that (450W-510W). And if you are now thinking that wow my 600W panels are actually going to produce over 1000W, well no. Maybe if you have two suns in your neighborhood...

Had similar thing happening with my Deye12K, but mine just stopped discharging @8% while batt cell voltages were around 3,18V. Found out that it was batt BMS which had SOC protection enabled, so just disabled it and now I can get down to 5% (3,0V). If I go under 5% it will start charging batts...

Nothing stupid with your question. There are two reasons that I can think of. First is snow as we can have more than 1m snow maybe once in a decade. I really don't want to clear snow around my panels as I have to do that with my 1ha (~2,5acres) yard already. Secondly studies show that backside...
