Daisy-chain AC battery inverters for comms?

I now have 2 x ME3000SP AC-coupled battery inverters running in parallel - supplying electricity to my house when there's no PV power. I am sure I've read somewhere that it is possible to use a single wifi logger to collect data from both inverters (I have a wifi dongle on one of the inverters, but ...

Re: Heat pumps in their many glorious guises in Camelot V home.

Here, we've got: 1 x 18kW dream ASHP to heat the house during spring/autumn where there's enough PV power to make it 100% renewable 1 x 9kW ASHP to heat pool spring/summer/autumn when there's enough spare PV electric to make it 100% renewable 1 x Samsung HP tumble drier for house (can't use the line...

Re: Making Methane in Swindon

What a stupid idea! Presumably to part wealthy idiots from their money for 'investment' purposes. Where are they getting their CO2? Bottled CO2 is actually quite expensive, and often made by burning gases like methane, as it provides nice clean gas. So chances are, this is what they're using. It cer...

double ME3000SP 3kW AC-coupled battery inverters upgrade

I finally got round to installing my second battery inverter. Previously, (on the advice of Pylon/Sofar), I had a 20kWh battery made up of 4 x 2.5kWh batteries and then a later addition of 2 x 4.8kWh batteries. Unfortunately, the batteries all discharge at the same rate, and when the 4 x 2.5kWh batt...

Re: Tesla mileage discrepancies.

The 'range' quoted for all electric vehicles tend to be rather fantasy-driven. In the old days, you have mpg at 30mph / 56mph / 70mph, and if you drove your car mainly at these speeds you'd see generally something similar to what was advertised, given correct tyre pressures and without excessive loa...

Sunny Roo 'parallel setup'

Im playing with some Sunny Roo inverters (very cheap on ebay at the moment). Trying to decipher what it says on p16 of the SR5000TL manual, it appears to say that if you fit one large string, you should use two short cables (with MC4 plugs on each end) to bridge between the second pair of string 1 i...

Re: CT coils for ME3000 inverters in parallel

Thankyou - perfect explanation! I've ordered the parts to get my slave inverter up and running, but they forgot to include the fuses for some reason, so I'm waiting for them to arrive.

Has OFGEM gone bankrupt?!?!

I've been trying to contact OFGEM over the last couple of months, as they've failed to process any of the last 3 RHI readings I submitted. As the next one is due, that means an entire year of unprocessed readings, which doesn't seem quite right. I've emailed them at various emails they provide (hi@o...

Re: Positioning of speakers in echo-ey room

https://i.postimg.cc/mzKcPjz6/pool-small.jpg Yes, pool building! I've been building it over the last 5 or 6 years. I should have gone for multiple speakers, but already got the 2 x 15" peaveys - the plan was that I could unhook them and use them outdoors if I needed to. At least wiring isn't g...

Re: Difference between ME3000 Versions

Yes, I did try working my way up through the updates. Initially I tried the latest version and thought I had bricked it. So I reflashed a very early version and got it working again, so then I worked my way up through them and found the most recent that worked. I would like to get it running the lat...
