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...
