I had to limit the output power of the new solar system. First impression after a few days...

Holy Dooley! What exciting past few days. After the installation of the new solar system, I could now really see its full potential! We have a lot of power. Too much power, to be honest. I really had to limit the solar charge controllers while I was not at home. Far too scary seeing over 250A going into the battery.
But today is the first day we unleash the beast and observe what happens when more than 12.000W of solar power charging the battery. How well will the BMSes handle this situation? Will the circuit breakers trip? We do a comprehensive observation of the system in different situations and monitor the outcome.
You will also see why shading does not matter any more.

Oh, one quick additional note... now that the whole system is up, check component heating during peak production (and also with your charge controllers unlimited and charging at max rate). Everything. The conduits, wires, junctions, battery terminals, charge controllers, inverters... everything. Point an IR temperature gun at everything. Always a good safety precaution to do a check like this at least twice a year.

no such thing as too much power. you need some “dummy loads”. I would suggest some large electric hot water heaters.. divert power from battery charging to the hot water heaters, once the batteries are full. you can basiclly have “free” hot water for use in your house. you can also install an electric pool heater, and have a heated pool for free as well 👏

@@nach335 yes, it is technically a waste - but also a rational choice. We are getting close to mid summer peak solar south of the equator. 6 months from now the daily production will be only about 1/3rd as much. Until there is some economical way to store massive amounts of energy for six months, it makes sense to over-provision panels.

@awo1fman Жыл бұрын

@@nach335 Absolutely wrong. Never having to worry about having enough power, regardless of the weather or other conditions, is the WHOLE POINT! Most solar systems are DELIBERATELY massively undersized because they want you to still be dependent on the grid. The installation companies have their hands tied by regulations that are written by power company lobbyists. The only reason Andy can get this done is because he's putting it where the grid was never connected. Otherwise the only way to do it is DIY, which is again illegal in many places because of corporate influence. If you don't have enough storage for at least 2 full days of normal use with no power saving behavior with zero power production and enough solar to completely fill your storage from zero to 100% then you're doing it wrong and being massively ripped off.

Ah, this solar stuff is like an addiction. We start small and it is quite nice so we decide to go a bit larger. So, we order more cells............and more cells. Then we realize we don't have enough power from our panels to support our larger battery. So, we purchase more panels and all the "goodies" to go with them. And then we realize we need more battery capacity. And the beat goes on.

If that is done right, you will always be overpowered on sunny days. This is not a problem, this is the nature of a well dimensioned off-grid solar system.

A powerful leaf blower for regular maintenance is best but also, not on hot panels. Again, great installation Andy!

@@camielkotte You may be right about about soap (or what kind) mild for sure, but you have to check with the manufacturer. I live in an area that has lots of sticky leaves and dust. The panels have a 15 degree tilt. Most of the time I blast it with a leaf blower but that gets only 75% per treatment. After a few months the accumulation is too much. So I can wait till winter for it to self clean or do with only half the power till then. Even tho I have “half cells”, I can’t believe how a few dozen medium sized leaves can destroy energy. I envy those that have steep panels and little local contaminations. There are after market “ceramic” coatings for solar panels but I’m not interested at this point.

Just a note on my 15kw grid setup I can produce during summer over 100KWh in a day, and I am a little further south, so your system has potential.

@OffGridGarageAustralia Жыл бұрын

I probably won't reach that as my roofs are facing East and West and I have a bit of shading in the morning and afternoon. Not ideal conditions but still far more energy than I need atm.

@dobrzpe Жыл бұрын

holy moly - YOU'RE RIGHT!! i've been a little concerned with the cascading-battery-BMS shutdown-overcurrent thing for a while now on my system... and yea! i *NEVER* thought that when the system goes into absorb/float it is in a constant voltage state and will only push the amps required. NOT the full amps of all controllers going to the max. so, at least, this alleviates any concern i have of this going on during absorb/float. thanks! it's still a *possibility* to have a battery/bms shut down during bulk and then divide the amps among the remaining batteries... but the chances of a battery/bms going offline during bulk is... well, a very low probability. wow. im ASTOUNDED at my incompetence! LMAO!

I would look at setting up DVCC Andy, that way you can limit the 250a dynamically, but still allow each controller to utilise their maximum performance if there is

@OffGridGarageAustralia Жыл бұрын

That would require the different BMSes to communicate with each other. I'm looking into this with the battery 2.0 first and see how this all works using the Seplos BMSes and batteries. Once I know more about it, I'll go and upgrade the production system as well.

I cut one tree down today increased my output 1-1.5kW! I’ve cut all that I need to with 34kW of PV. When you’re totally off grid, heating with heat pumps, heating your water with electric water heaters, you need every last watt. 65kWh yesterday, 124kWh. That’s with the shortest day coming up in about one month.

Excellent results, I love it! So the tilted panels are running hotter, my guess is it totally due to the colour as the tilted carport panels appear to be darker (Blackish), while the west roof panels? Are a bluer colour. I wonder if you laid one panel flat if its temp would increase any due to less ventilation? Also, despite ur very good reasoning against having a 2nd battery, my thoughts why a second battery would/could be useful are as a quick charge backup for the Tesla, so you can fully recharge at any time if need be. As far as burning More of the excess energy, I can only suggest to get a Dyno and put the tesla on it. Great job. Cheers

@OffGridGarageAustralia Жыл бұрын

The tilted panels have a lighter colour than the shingled panels which are just black. I think it is because I measured the black panels at the bottom where cool air stream under the panels and the tilted panels, I measured at the top where the hotter air comes out in between.

It's off-grid. As soon as you connect to the grid, you have many regulations and restrictions to take care off. You cannot have unlimited solar and feed-in while being connected to the grid. As long as all this red tape exists, it's not worth it.

This was great, to see your face at those numbers. And you answered my question at the end on the panels - so its not that those panels are running cooler - they are just better? in terms of kwh/w of each setup they do seem to be kicking the shingled panels ass. Or maybe its just that they get less shading - and hence are hotter - but still grabbing more photons.

I think the values are also higher because the specified Wp are mostly measured with 1000W/m² light power, I remember in his place he measured always about 1250W/m² light power. Here in germany we mostly have the opposite situation, but in Australia it seems you can expect to get some more power then advertised :)

Andy I mentioned once before that I thought that you are likely have a large over supply of energy with the new panels. So are you considering moving as many house loads as you can across to the shed system, so that the house solar system can throw all it's generation into the grid and get you some of the 0.49 cents a kWh back into your pocket. It seems such a shame that you could be 'losing' some of that great shed power ATM. I know I would be beside myself if I was generating so much power that I had to throttle it back, sort of like spilling SPATs on the ground lol🤣
