All backed by a 55KW three phase diesel generator to give it a boost when needed. Will be upgrading to 10KWp soon and going on feed-in tariff. Lots of spare power available...

So all I need is a mini power station 😉 Thanks for the info

March 26, 20197 yr 1 hour ago, Dan said: So all I need is a mini power station 😉 Thanks for the info Well, it has to serve a big house. You see when you go house shopping the wife looks at the kitchen. All I saw was a beautiful large north facing roof at just the right angle.😍 The diesel generator was already there (the house is kind of built around it - it has its own sound proof room, you cannot hear it when it is running). But I always wanted a nice clean solar power system. To be sure - it's not perfect - I would not mind bigger inverters, MUCH more battery capacity and more PV. I am adding more panels soon to make the feed-in tariff work but I can't go more than 10KWp - that's all the space I have left on that roof gone and other roofs are not that great due to position and shadows.
March 30, 20197 yr I have a 4kw infinisolar plus hybrid that is connected to the municipal power. It kan supply additional power as it is a hybrid. It has run at 120% load happily driving th pumps from the municipal side. I also have a 2.2kw borehole pump that I can run via the inverter. The starting amps for the Franklin borehole pump is 35 amps which settles to running 14 amps. I normally take the inverter out when I fill up my 2x5kl tanks. I prefer the bypass mode as it shows a load of 98% with the Franklin running. If there is load shedding I’ll start the generator to drive the borehole pump to fill the empty tanks. I have never started the borehole pump from the batteries alone. I use a seperate pump (from the tanks) for my garden irrigation. I don’t want to subject my inverter and batteries to unnessary high loads unless there is no other way out. Edited March 30, 20197 yr by Johandup

I pulled our borehole pump over the weekend (installed by the previous owner) and found we're using a 1.1kw Franklin. Its running at about 8 amps once it gets going. Based on your experience it sounds like the 3KVA Victron may be able to the handle it.
July 23, 20223 yr Question regards a borehole and solar system. Have a 120m deep well with a 3 phase pump. Wanting to go off grid. Have a thought of using a solar pump 12 x 335 watt panels to lift min 2500 l per hour into my tanks. Will only really need 2 hrs a day. So for the remainder of the 4 or 6 hours, use the panels through a DC contactor to feed into my solar controller and 10kw lithium and 5kva victron for the house. Is this viable? Or should I rather find a pump that would do the job at 220volt from my inverter and be done with it? Thanks in advance Greg
