Nice one

This should do it. I logged a call last week and had a reply the next morning confirming it was enabled. Also you can ask them to update the inverter firmware as well. I needed to do this to get it working with the S3 stick.

One thing to look out for post inverter firmware upgrade is grid standard. For some reason the inverter went to some Brazil standard and got a grid over power alert. Set it to ESB-Micro and no issues since.

They are Pylontechs in how the communicate with the inverter, but they have prismatic cells and not pouch cells. If you do buy, make sure to insist that they send you prismatic cells.

Got the remote access now. Guessing the soliscloud integration in home assistant hasn't been able to utilise that yet to allow for automation?

Did anyone else get an app update that now includes "service" module to the right over "overview". Inside it lists "local operation", but i've no idea what that does.

jkforde

did the update and in their development wisdom they've removed the usage stats under the graphs, that team needs a senior UX member! then again, maybe it's a good sign that they're fixing\optimising it and will bring it back

Yeah. I miss that view. I've a spreadsheet with unit cost, FIT rate, units produced, units exported. And from that I determine my savings so far and an expected payback period. Copy/paste into the spreadsheet is more difficult from the hover tooltip from the graph.

Finally got around to setting up the batteries to charge over night thanks to the info on this thread.

Just one question/concern, I have two 2.4kwh pylontech batteries so the charge is set to 50A by default. I noticed it was hitting a little bit higher than that though, charge current peaked at just over 2.7kw (which is more like 52A I think?). Is this normal or should I try lowering the charge limit by a few amps?

Just getting battery (re)installed today, and have signed up to Pinergy's D/N 5c/40c with a FIT of something like 25c.

So obviously, my plan is to charge battery and car, and heat water, in the 3hr night window at 5c a unit. During winter the battery will deplete during the day at some point and that's fine.

But during the summer, With the 20c difference between FIT and night rate, it still makes sense to charge at night and export my solar during the day, and only top up battery enough to get from dusk to 2am. However, what I have been thinking is, would it make technical sense to discharge my battery from 1230am to 2am (and get FIT) then at 2am start charging again? On the face of it, it would be commercially worth it but would the additional strain on battery be worth the extra few cents a day in the brighter months?

50A at 230V is 11.5kW (Watts = Volts * Amps)

Even though the setting is at 50A, your batteries are probably limiting that.

It's 50 amps at battery voltage (51 ish) so more like 2.5kw

see the specifications label on top of their 2.4kwh battery, charge voltage is 53.5V

Stupid question but I'll ask anyway:

If my inverter will charge the batteries at 50A but the breaker to the shed where my inverter is connected is only 32a, will my inverter trip out the shed breaker?

Not a silly question. The batteries are charging at 50A but not at 230V AC. The battery voltage is 51.2V DC so 50A * 51.2V is about 2.5kW. This is about 11A at 230V AC. You've got loads of headroom with a 32 breaker.

Never even thought of that.

Gentleman. Thank you.
