Cheap grid tie solar setup (600W 3kWh/day)

I needed an upgrade for my solar setup since the utility bills got outrageous. The cheap grid tie inverter is easy to setup and saves me 1€/day now. I tested the microinverter and it's working fine making 3kWh/day with two 300W panels. The highest output I measured with my clamp meter at was 2A AC which corresponds to about 520Watts. That's nice because I didn't spend a penny for the mount. The app allows to control the output so you can limit it if you need.

Hey! where did you get the panels from?
your link shows flexible ones from Ali but that doesn't seem to be the ones you are using

Great stuff. I did something similar but you need to consider WIND. At some point you will have strong winds from the wrong direction. I used stainless steel wire to strap the panels to a fix point. Before this, wind moved all my panels but I was lucky. No damage but only due to luck.

Having the mains on the roof is still safer than having high voltage DC (many panels in series), which easily can start fires if not wired properly or exposed to moisture and therefore producing arcs. As long as your protective earth is working (testing the breaker) everything will be alright when a fault does occur

And now hope that you don't get a Beaufort 11 storm any time soon! If I would just lay them down like that on my roof, they would not last a week.

I put 2 250w panels on my shed roof a few years ago, and it has already made over 1.6MW of power in that time. Not bad for £100 of panels and a £70 inverter :).
I brought the DC down from the roof into the shed, where it goes into a DC circuit breaker, that way I can connect whatever I want to it without climbing onto the roof which was never really designed to have people standing on it.

I just finished to installed two 420 W panels on the wall of my house. I've bought all separately like you because of the high prices of kits. I had a APSystem micro inverter that seems to work only in certains security condition. For now I'm just at the step of connecting all things together and see if all is properly working!

In France you have to declare to the network manager company that you are going to install a micro inverter and be able to send in the public network the excess of electricity produced and so you have to give them a proper certificate for the micro inverter. It's why I didn't bought the one you get because no certificate was available in French... they only accept them in French!

So I hope this will work properly as I thought! Thanks for sharing your experience.

Easy install and well explained. You could increase your harvested energy if you tilt the panels a bit more. Especially in winter.

Your workshop look like it's built as a bunker!
The one foot of poured reinforced concrete roof gave it away :)

Now in NL: 3200 watt allowed on a seperate group, or wasmachine group with a" pv divider, breaker" added.

[PetRatty]

nice video, I've done the same for the last 2 years, 600 watts at 24volts and 100watts at 12volts into battery storage and then into grid tie, pay only for 1Kw or their abouts a day (40P). It's the way to go, switch my gas boiler off too so pay nothing for that either

[IanScottJohnston]

Nice work wonder, aren't you worried about losing the entire solar panels etc next time a big wind storm comes through?

[silverismoney]

Nice. We're not allowed to do it ourselves in the UK. Well I mean if you wanted to do it legally then you would need an "MCS" approved installer to do it. I have two solar arrays and I wish I had space for more, so I recently put one on my shed roof and used an MPPT charger to charge two LiFePO4 batteries and then I run everything in my shed workshop from that.

iv had one 250watt panel on my garage roof here in UK for 8years with a Replus micro inverter been great no problems, i refused a smart meter i told them the meter ant that smart as it will charge me for power, for pushing power back to them . i have also put an aluminium cross piece on penal and weighted it no storm has mover it an inch yet. as far as getting to trouble as long as you don't have an analogue meter spinning backwards then no problem, if you are doing DIY a few panels only is the way to go, as it grid tie say 400 or 500 watts then thats best way to go you will be using most of that output. A word on cheap Chinese invers they don't last long, Enphase is the best you'll probably get a life time out of them, i got 6 months form cheap Chinese one, i'm on 8th year Renesola Replus micro inverter but i can't find them anymore as i have jest got another 235watt panel, Enphase are expensive, may have to bite the bullet .

Due to the increase in energy prices, I do not use the lighting in the toilet ... But I have to wash the floor more often ...

[CTCTraining]

I couldn’t quite work out if you were planning to mount the unit flat under the panels and trust that the seals hold ? In the past mounting vertically and leaving a small moisture exit point at the bottom edge has worked for my outdoor projects. Sometimes a small piece of gauze helps stop bug visitors. Good luck!

[DantalionNl]

The cheap micro inverters often have insufficient filtering resulting in many spurious harmonics and failing to comply with EMC regulations. They are by far the most problematic consumer RF noise source now a days.

[michaelschecker]

thanx a lot for showing inverter inside quality is better i thought.
Now i have a new project for summer. To be bit save for brown- or blackouts i will build up an island solution for solar disconnected from the grid.

Your neighbors are waiting for the next storm, then the gods brings them free solar-panels💯

[powermod]

You should definitely make the panels resistant to wind / storm. If you are unlucky, on strong gust is enough to blow them away.

Hi, I have the same electric car. Waiting patiently for your solar charging video :-)
