Jladans Solar setup

That’s the joy with Victons, I remember in training that you are able to pull higher than the inverter rating and will sustain the load till it reaches its thermal threshold before restarting.

That works well for short peaks, then. Like where the tumbler, washing machine and dishwasher decide to peak all at the same time
 
So super pleased with my setup currently , our area has been down since early yesterday morning and while running lean we got through the night with 40% still on the batteries which are currently recharging and allowing us to turn on our geysers.

Proving to me as long as we have sun we can now get by pretty comfortably without Eskom. Hooray !

It's a great feeling knowing that when push comes to shove, you can make a plan to do without Eskom.

We had a 60 hour outage last weekend and I got to morning with 20% left every morning. Granted if the weather was bad I would have been fooked, but that can be remedied with more storage and panels...

Great setup @Jladan :cool:

Yep, I have been amazed at what our little 3kVa MultiPlus I has handled over the years, I recall a single restart a while back.
 
Still no power and clouds for miles, let’s see if enough sun will penetrate to get us eeking through the day, certainly no geysers today :( and I suspect tonight will suck unless I can miraculously source a rental genie and figure out how to hook it up to gen input on the Quattro
 
Quite a lot because I went team blue and got lots of extras , was 280 with install and the cabinet

It is worth it. Nice setup, may the sun bless your panels and batteries with many, many photons!

Maybe a generator for topping up as well? For extended overcast days?
 
So I have a probably very noonish question for the experts, I’m looking at adding more panels , so I’m thinking of just another victron mppt and another 3000w of panels north facing. This will bring my total on the roof to 12000w. What I’m wondering is whether this either overload my batts or inverter, or if and when I go over the inverter and batteries will just ignore the additional power. I’m currently running a 8kva victron Quattro and 7 pylon 3000cs.

My current setup maxes out 6000w in winter hence me wanting to add more, but concerned about summer where I do already hit 8000w max on a good day. So I would imagine I could hit 11000w with the proposed setup on a good summers day.

Thoughts ?
 
The inverter should simply clip the maximum input from my understanding.

At least that’s the case for Sunsynk but I can’t imagine it would be much different for Victron.

Usually Solar arrays are overspecced for a given inverter for this very reason.

You have to take in to consideration that Victron works a bit differently to other inverters with built in MPPT’s in that you can add additional MPPT’s as and when you need. In theory this means that even though your inverter will only invert 8kVa worth of DC to AC for use in your house, excess DC supplied to the DC bus bar could be used to charge batteries. I say in theory because I am not sure if the Victron control unit will allow this or if there is a physical limit on the DC side that will limit this.

yup this is exactly what I'm trying to confirm
 
It shouldn't be a problem adding another pv string and MPPT. That's exactly what I have.

For the last ten years I've had three pv strings totalling 12kW, attached via 3 x Outback FLEXmax 80 MPPTs to a 12kW MLT PowerStar II and 48 x lead-acid batteries. The batts were end of life so I took the opportunity to update the system.

I recently installed a Victron Quattro 10kVA and 6 x Pylontech US3000Cs.

Each pv string has its own Blue Solar MPPT 150|170-Tr.

So far no issues.

That is exactly true. My 5kva victron charges the battery even when inverting at max. That is why I have a record of 51 units of solar generated in one day which would be impossible inverting at max only.
