I am grid connected. Any excess power from panels or batteries (minimal) goes to grid. Trying to balance on your own excess power is too expensive & complicated. IMO I use 240 Volt dedicated battery changers instead of solar chargers as I think they are better suited to charging LiFePo4 or any...

The current average life expectancy is 72.6 years, and we can assume that people do not begin browning toast until they are at least 12.6 years old (60 years to brown toast). There are 52.1429 weeks/year * 60 years = 3128.574 weeks in this time. I brown toast about 2–3 times in a week, which...

Thanks svetz... Updated Image from kundip: .

Note: Over the last three years I have tested so many combinations of devices you would not believe. Starting with a computer UPS that 4 different electricians said would not work. What I have distilled is our best observations, that we have shared, over that time. OK, so the Micro-Inverter...

My thoughts. Unless you have limited space: If you want to put in tracking systems it is cheaper to put in more panels. If you want to pay someone to wash the panels it is cheaper to put up more panels. If you want to put in optimizers after the original install it is cheaper to put in more...

Feast: Creating the problem of way too much energy is the first post. It means you can have the fun of figuring out how best to use it. I set up two old 2400 watt fan heaters with WiFi timers. They were only needed 10AM until 2PM to shave the top off the peak export time. Initially I used...

Awesome. You will survive a nuclear war!

Thanks for reply. You have inspired me to post my setup. I will post in the next month.

Mine is similar. I have 1 Envoy micro inverter per battery. You can have as many micro inverters as you like. I have one 24V Battery with 5KW AC capacity running every night for 14 hours @ 300W AC (240 V) Also one 24V Battery with 1.6KW AC Capacity running every night for 14 hours @ 200W AC (240...

Has anyone got this to work yet please? I have a 24 Volt Battery (3.2 KW). I have ordered a Buck Converter from Amazon: Dasiter 600W High Power DC to DC Boost Converter DC 12-60V to 12-80V Boost Module Board Step-up Transformer. I have an Enphase M215-60-230-S22 inverter. Recommended maximum...

Dave wrote back & said he cannot do it. He has too much work on & family commitments. I offered to pay for the 6,400KM round trip including his fees, accommodation & food. No luck. Thanks for the suggestion.

I have an Enphase M215-60-230-S22 inverter. Recommended maximum input power W 310 MPPT voltage range V 27-39 Operating range V 16-48 Looking at Doctorbass on Youtube Watch?v=GxSafeeUWB4&t=525s The battery input voltage has to be above the maximum MPPT voltage (39 Volts). ...But below the maximum...

I have written to The Electric Viking in Melbourne to see if he is interested.

A big thank you for this comment. It makes me feel like my (albeit kind of misguided) work may have come to some good validity - after waiting a great deal of time. You and a couple of others have shown good interest which pleases me no end. I just hope it all stands up to scrutiny.

I crimp & solder every joint. No dielectric grease. The EV Power came with a shunt & a reader but I disconnected the reader & I am going to take the shunt out. I just don't use it. I can see from the Envoy data what each battery is doing easily. No thick cables - just 20Amp cables. I have...

FYI 200W Micro Inverter: https://www.aliexpress.com/item/1005004135690082.html Not something I can do: https://github.com/atc1441/NETSGPClient

I will try to get this reading to you. I tried another brand new boost converter - exactly the same model - but I just cannot get it to control the current. This is the eighth time I have tried to replicate it. (5 Boost Converters the same & three other types.) Why the first one is working I do...

You can put microinverters anywhere. I have mine at ground level where I can easily replace, work on them or check them. I put all my microinverters at ground level. Easily accessible. Originally I laid them out but now I just hang them up on a rod. None get hot.

Please lay out your questions so they are easier to read. I use a 24 volt system to keep each in a small package size. You can just plug the Enphase Inverter straight in to the 24 volts - the inverter starts producing after about 5 minutes. Please look & read at pics I have supplied - I just use...

I haven't seen bare copper in any twin core solar cable in Australia. It is all tinned along with the lugs. Tin and tin oxides are known to react with phosphoric acid to produce highly insoluble and relatively inert compounds. I didn't know your twin core solar cable had bare copper in the USA...

Nice video. Neat work. Looks like you had a lot of fun.

Starlink normally come with its own router & POE injector. They are selling the Aerial, Router & POE injector with about 40 feet of network cable for ~USD $303 in Australia. It all comes in the one box. The main power usage would be by the router easily. I just fitted a Starlink system in Mt...

OK. That is difficult. I notice in Australia the energy meters calculate by the 1/2 hour to one hour - not by minutes. So if you use 1 KW at the beginning of the hour & put back 1KW before the end of the hour the meter will show zero consumption. I think it would be the same in the UK. Please...

OMG Unbelievable.

Really really nice work. Great article. Much appreciated.

Nightmare stuff. Buildings that hover off the ground might work.

BentleyJ - Thanks for your article. So Far our system has cost US 0.48 cents per unit. We have 42 panels ~300 Watts Each. 18 KW of Batteries Also a Power Transfer Twitch & Inverter for UPS which runs lights, internet, computers, fridges, fans & TV's on power failure. Our Total Cost USD 19,602 It...

Well it's worked for two years so far. Re properly sized to handle load. Keeping the voltage at the low end seems to work fine. The imicro-nverter can take from 20v to 46v. I stick with 24v. This gives me 200w @ 240vac. I do have one set up from my original experimentation that has a boost...

I have decided to buy these 6 x 50AH 12V batteries for USD $467. They are 8 years old. Included is: 1 x Victron 12V 30amp blue smart charger which I will sell. 7 x 40W good quality, caravan type, solar panels which I will sell. 1 x 1500w pure sine wave inverter - will sell also. Bus bars to suit...
