Sell the 8kva, buy a 12kva add the flat to the house inverter

Can you run the geyser on the non-essential output to be supported by solar ?

I cannot 100% simulate load shedding because I cannot simulate a "brown out" . 100s of other Victron users are also suffering from the same issue. Testing it with a multimeter, there is also a short between live and neutral on out 1.

I've seen a few international posts but thanks for the reminder

Background : we have blackouts in South-Africa (Loadshedding), power is cut for 2 hours at a time in my town (Nelspruit), depending on the stage between 1 and 4 times per day currently. I bought the Victron Quattro 15kva with 28 panels, 2 mppts, cerbo gx, color screen, smart shunt and 2 x 10kwh Lithium batteries. Was installed by a Victron accredited installer. The purchase was made to avoid Loadshedding and not be affected by it. Between every 3rd and 6th time the inverter will shut down completely, whether my loads are 200, 1200, 2000 or 4000 watts, doen not matter if the batteries are 70, 90 or 100%. If it's during the daytime it will start up again within 2 minutes if there is sufficient sunlight. During nighttime it wont come back on at all until the grid power is restored. There is a short on the battery terminals so the batteries goes into protection, It won't turn back on again, even if I turn the unit off and on, only when the grid come back it will turn on. The installer updated the firmware to the latest version. He set the cut off voltage to 210v to not follow the grid down for a "brown out" I cannot replicate the problem by turning of the main grid power, then the inverter switches without issue. Any help would be appreciated

Have you checked your neutrals ? Had 2 similar issues, one where the live was going through the el and neutral not, and one where where suspected a light circuit was connected to the geyser neutral, we had to draw in a new wire for the geyser, just count find the fault. Also check if the el is not faulty

Thanks

We have a few Victron systems in our rental properties, looking to save a few Rands and go with Sunsynk on a few more. Does the Sunsynk have a fused/Protection on the MPPT or do I still need to fuse/surge protect it tia

Goo day So after seeing the "professionals" do a few of our installations, I thought I can do it just as well or better for cheaper. Yes I know that I will still need a COC, I will do most of the work myself and then get a professional to go through everything and do a COC. It will be 3 strings of panels, each double fuseholder will kill the + and - of each string. are the way that I've bridged them on top correct ? tia

no all the systems are 48v freedom won batteries 3 are Victron 15kva Quatro's 2 are Victron Multi plus 2 5kva
