MB Models three phase solar and battery system Part 1! 

Another great video, looking really professional 👍

Good video, with such a big roof space was any consideration given to to mounting some panels to make use of three aspects giving a earlier and later solar window

Great video, do you have many issues with Sonnen battery storage? I’ve installed one and had constant inverter issues with it!! Very frustrating, would not recommend with the experience I’ve had with the SB-10 unit.

Any reason why DC coupled SolarEdge batteries were not chosen over the AC coupled Sonnen batteries?

What Wholsalers do you buy the sonnen batteries from??

Thanks guys, great video. I was surprised at the low angle of the roof mounted panels, but you are the experts. I am interested how you got your panels secured to the roof, did you have to drill through the waterproof layer or are the concrete slabs just weighing down the metalwork? OMG though, who did your sound levels? The music came on and nearly blew my speakers out, turn down to 5% volume. Music stops, voice level is really low, back to 100% volume. Why do you want your viewers to have to keep twiddling their knobs?

Really enjoyed this video. Lets hope there is a part 2.

@5:25 do you use any energy logger prior to setting up in order to understand a client's consumption? Place one on a client's energy meter/main circuit breaker box for a 2-4 week period to better understand how energy is used.

Great video Sam 👌🏻👌🏻👌🏻

Great video Sam 👍 . How do you know which brand of PV module to choose there's so many out there do you just have your set favourites or do you try use lots of different types? Thanks

Did you suggest the possibility of using bi-facial panels? Should produce aprox 10% more PV, more if they painted the roof white or light grey.

I notice that most of your installations have strings and panels with or without optimisers feeding DC power to a large-capacity monolithic inverter. Do you ever use micro-inveters on panels thus feeding AC from each panel from the roof to electrical infrastructure? I know you need an inverter to then convert to DC for battery storage and the panel electrical components will be different. Is it a regulatory compliance issue that makes either type of PV setup preferably in your market or some other consideration? We here in the southern hemisphere have both types but domestic installations seem to be predominantly moving towards micro-inverter installations.

What's the point of optimisers on a flat roof with no chance of shading?
