SMA inverter fault VAC BFR, what is this?

[@ianhelsbyservices]

Glad to see it working. We all need to generate our little bit, especially when the import cost doubles in April. Worth pointing out volt drop across long leads too. I swapped a 50m 1.5mm2 extension cord for a 2.5mm2 as the smaller reel lost 12% in voltage.

[@TheInfoworks]

Ian, volt drop is a killer with all of these systems. I am going to move some inverters closer to their panels to reduce this, cheers

[@kennyward4674]

I got a bit of chuckle from that one😀 Glad it was a simple fix and at least you know what the code is now.

[@TheInfoworks]

Kenny, yes a bit of a DOH! moment, cheers

Hi Andy, Not sure about that socket outdoors without protection. Could get corrosion on the plug pins and also the fuse holder. Thanks for the video.

[@TheInfoworks]

Hi, oh yes, exactly, this is a temporary set up, cheers

[@noakeswalker]

SMA inverter error codes VAC-Bfr and VAC-Srr seem to be internal codes for 'grid voltage too low' and 'grid voltage too high' respectively. Grid frequency out of range error codes are FAC-Bfr and FAC-Srr also. What 'Bfr' and 'Ssr' are short for, I can't work out. Just looked this up online, and am passing it on as I find it. If you don't have a label printer Andy, and I _really_ recommend them, you could do worse than use masking tape wrapped around and a permanent pen marker to label your cables outside and in the batt shed. Cheers, Dave

[@TheInfoworks]

Dave, so VAC BFR in this case refers to AC low. Normally I colour code wires and that extra white mains lead was from testing a Solis, then forgetting it was there, cheers

Who doesn't like a quick win! 😎

[@TheInfoworks]

Matt, especially when it's caused by a simple no harm mistake, cheers

[@mouldyboats]

Those caps are hating life. Looks like your next inverter problem. Recap with Nichicon's and get it out of exposure.

[@bootsowen]

I wondered about putting a multimeter across ac. But a true rms meter would be necessary.

[@TheInfoworks]

Owen, as you see it's fine unless you need to be very accurate. It let me know there's mains power there, cheers

[@sim6699]

Are any grid tie inverters really reliable or come with a 10 year guarantee?

[@TheInfoworks]

Well this one may be 15 years old. The Solis had a 10 year guarantee. it all depends on the quality of the installation, cheers

Help, sorry bad inglish. Omniksol 2k tl Isolation fault , fault in inverter, where do i start looking? Relays is new.It is possible find schema?

[@TheInfoworks]

are you sure the fault is in the inverter, many times it is in the panel wiring. make sure your DC wires are strapped up and not touching earth, cheers

[@christianlarsson6065]

@@TheInfoworks yes absolutely sure, also tried 150 vcd from battery

[@TheInfoworks]

@@christianlarsson6065 Difficult to define, maybe start checking the capacitors. Otherwise replace the unit with a second hand solar inverter, cheers

Thank you

[@TheInfoworks]

No worries, I hope you have subscribed, cheers

[@neilobusk]

I know nothing about solar.....apart from using the sun..lol learning... N x

[@TheInfoworks]

Neil, time to gather some, cheers

Help inverter won’t turn on

[@TheInfoworks]

do you have AC and DC power at your inverter?

[@cherrabimohammed7342]

@@TheInfoworks hi, i meet the same issue it will not run... i have a 480vdc and 230vac but it wil not run it's a sb3800

[@TheInfoworks]

@@cherrabimohammed7342 is the 230v AC getting on to the board? cheers

[@cherrabimohammed7342]

​@@TheInfoworks hi, it run wel now... The mistake that i did was to run First the DC then the AC and normaly you need to start the inverter First then activate the DC switch
