Thanks - that's helpful information. 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.

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

Thanks @The Terrible Triplett, really informative

Understood, so the inverter feeds enough back into the main DB to reduce the usage, but not enough to push back into the grid. Why does using AC_out2 complicate things? It seems to be the intended purpose and removes the need for the Carlo Gavazzi. I assume that there are some practicalities I haven't thought off?

What setup do you have running that?

Thanks @[email protected] for the suggestions, I'll probably test it out on the inverter to start with, but it makes sense to switch to the low power pump long term to make use of all that solar during the day. That's what I'm trying to figure out - can I put the pump on the essential circuit to provide us with a backup water supply in cases when the grid and water supply are both down. Edge case, but its happened to us So will the Victron use the output from the PV and then just take the balance from the grid? Or will it switch the entire load the grid and the potential PV generation is lost if batteries are full?

Thanks, I would never have thought that would even be an option. I'd still like to figure out if running the existing pump off the inverter is even an option. Is it possible to damage the inverter / batteries testing a load like that, or would the pump just struggle to start / everything shuts down?

Thanks all for the replies 😀 The pump runs the irrigation system and we use it to top up a JoJo for a backup water supply. I'm not concerned about the irrigation during a power failure, but we may need the pump for the JoJo. I'm trying to figure out if that is feasible and if so, is the 3KVA Multiplus a good choice? Or should I just disregard that as an option? Long term sounds like the better solution would be a low power solar pump that empties to a storage tank and then run things from that. That would involve changes on irrigation system which I would have preferred to avoid.

Hi All, I'm looking to invest in a solar system with the primary aim of getting some independence from the grid. We have a borehole and the plan is to run that off the inverter to cater for scenarios where the municipal power and water supply have both failed. Will a hybrid inverter be able to handle the startup load of a 1800W borehole pump? Or are there better options for that? I understand that the regulations around the grid tie in will limit us to a 3KVA inverter on our 60A supply and I'm planning for the following Victron setup running ESS: Victron Multiplus II 3000VA - 2400W continuous (peak 5500W) 2 x Pylontech US2000B - 2400W continuous discharge (peak 9600W) SmartSolar MPPT 150/100 2kWp Solar Array Venus GX Thanks!
