do you have a pool or spa running ? I guess its a plus that you have so many hvac units vs fewer larger ones. there has to be a way you can lower costs of hvac by shutting down/raising temps of some areas at some times. cant just set 11 hvac units at 70 without a huge bill in the summer. are...

2012 SMA gridtie inverter just wont die, wish it would

North East Texas Totality

I got it to fit on my 2 lv6548

Main reason I wish I got the Iotawatt instead of the Vue is that you can keep the data local and send to Home Assistant. with the Vue it only sends home assistant the every 1 minute data not the 1 second data which I would like.

OK. interesting post. maybe presented in a slightly know it all manner.... I agree that trying to get a fully automatic/smart load shedding/complete backup/while away from home/never fails system may require a crack pipe and/or a millionaires budget to get maybe 90-95% is easily doable, and...

even the vue 2 shows what you send back to grid. it shows what the inverter produces and then subtracts what your loads are, showing "net production" which is sent back. I guess its not an actual measurement plz share any info you get on the vue3, my guess is they will always force you to use...

best bet is to start with an Emporia Vue monitor system. You need to figure out where exactly all that power is going. they are pretty easy to install, does not require an electrician.

I have been using 2 of these inverters for 2 years now, no problems Watts247 is selling them new for $1099 each, if you can use the 30 percent tax credit that makes it around $800 each for a new one. Can not use the tax credit on a used one If you can use the tax credit, I would not pay over...

there is a cheaper way that many people use for backup power you can install a generator interlock in your main panel and a generator inlet box the way it works, is that when power is out, you turn on the breaker connected to the generator interlock switch the mechanisim (interlock) then forces...

these are "double throw" transfer switches with 3 positions. Utility-OFF-generator not to be confused with a disconnect switch which has 2 positions On-Off you need a double throw, 3 position switch for what you want to do

both 100a and 200a manual transfer switches are avbl, even from home depot 100a is $219 and 200a is $544, both made by GE just install the transfer switch between the main panel and the subpanel and add a generator inlet box to the transfer switch what size breaker is in the main panel going to...

probably not worth keeping one for functional reasons. maybe worth it for cosmetic reasons if they are on your roof, street facing etc. with only 6 panels in operation, not having a spare is not a huge risk

yes, thats right. also as CRenner mentioned above, look for any stickers or info on the panel that indicates what amp the bus bar is, just to be sure it is 200 vs 225. for example, I just ordered a square D QO panel with a copper 225a bus bar with a 200a main breaker. the square d QO is a more...

he is correct .I did not research to see if a 175 is avbl for his model panel. if avbl thats great. all models have a 150a but maybe not a 175a the calculation is the bus amps (200 in this case) x 1.2 = 240 amps max. now subtract the PV breaker size (50a in this case) and you have 190a max main...

jus re read your post, so you already have the 200a panel.... so change out the main breaker to a 150a breaker, and use a 50a pv breaker no subpanel needed as long as your main panel has room for the pv breaker to be added

this panel has a 200 amp bus bar, and a 200 amp main breaker. this makes the max PV breaker you can use 40A that is to comply with the 120 rule your solark 12kw puts out a max of 37.5 amps, multiplied by the 1.25 rule means it needs a 50 amp breaker. that is too much for a 200 amp panel with a...

what is your charger source priority set on ? what is your output source priority set on ?

I do not see a problem with your proposed setup, at least here in the states. I have 2 grid tie systems and 1 off grid system, in a similar setup where some people have a problem is when they are wanting to put the AC output from the off grid inverter into a panel that also has the grid on it...

thats too close if you ask me. how many days might it get even close to 10F ? if just a few times a year maybe disconnect the panels ?

yes, do a 5s2p. how close to 250v are you at 10F ? I have 2 of these inverters using 250w panels in 6s2p almost impossible to get much over 6000w total even though they claim up to a 8000w max input

do you have any pics of your current main panel and location where you would be installing the inverters and batteries ? same building ? how far apart ? I would not design a system for only 120v loads. there will come a point after you install that you will wish to expand. it might be that on...

I have both grid tie and an off grid system. In some conditions I like to be able to control if a load is on the grid or on the off grid system. I installed a switch which allows me to control this. this switch controls one of our mini splits (normally on the off grid side) I may install another...

what is this automatic updater ??

I also see that the Warning 412 is now gone. this is not listed in the manual and SS said it was a temp sensor issue. May have actually been a grid over voltage warning

I just got it online my AC volts are always a bit high, right now 255.5v on the inverter under Grid Code, there is a setting called syncronization Range , and the Voltage High setting was around 252v, I changed the growatt setting to 257v and it came online

I have a 400a meter base with 2 outputs, each 200a output goes to a separate 200a panel on different buildings. each main 200a panel has its own grid tie system 1st is a 6.44 kw with sunnyboy 6.0 inverter 2nd is 7.1kw with the growatt 7.6 inverter the growatt is once again in standby mode this...

its some kind of temp warning, but the inverter is in climate controlled building the warning seems unrelated to me

I have the 7.6kw version happened to me again this morning. then turned on around 1220 pm mine did this the first day I installed it. stuck in standby. two days later it turned on when sun came up did it again last month, then turned on at 430 pm that afternoon did it again last week, then...

My POCO approved 2 separate grid tie inverters. each feeding into main panels on opposite sides of a 400a meter base. they both do shut down with loss of the grid. using this same setup right now

I have 2 of the original 250v inverters. 2 years now, never an issue keep in mind if you ever want to go to a 240v system you will need 2 of these inverters and a second might not be avbl at that time. with the 6 panels you have with a VOC near 50v you will need to wire as 3s2p to not exceed the...

Thanks just looked at todays data the new 395w panels peaked today at 6.1 kw from 7.1 kw capacity = 85.9% the old 250w panels peaked today at 7.4 kw from 12 kw capacity = 61.6%

each of my 3 ironridge ground mounts cost me about $2000 - $2500 DIY, will have to run some numbers to see if it makes sense to keep the old 250w panels and build another mount. at some point soon, you wont be able to get rid of the 250w panels for free. Im 40 minutes from signature solar so...

can you give info on how your array is set up with the 2 lv6548 inverters ? I have 2 of the lv6548 with the 250v limit, currently using used 250w panels. each inverter has 6kw total with 24 panels in a 6s2p going to each mppt I assume you are using the eg4 chargers to avoid issues dealing with...

are you wanting to sell excess solar to the utility company ? or just use the power to reduce grid usage ? usually here in Texas selling back power is not a good deal
