Victron Multiplus 24v/5000

Hi there, my client had a 3 KW SMA with the 5kVa Victron in hybrid config, wanted more panels and wasn't too happy that the Victron didn't cycle the batteries deeper and also didn't want to spend more money on inverters. Opted for 2 x Axperts with now 4.5KW of PV panel array and is planning to add more panels and batteries later as the 2 x Axpert can take 6KW of panels in total. I already sold the SMA to a client in Paarl whose feeding back to the grid. I don't know if you know the Victron - you can't hook solar panels directly to it, you need a charge controller or grid inverter for the PV side but, it is an awesome piece of equipment for a hybrid system with many different setting capabilities. Personally I would have rather kept what he had and rather would have tried to swop the SMA for a 5KW SMA.

Agreed. I'd have kept the Multiplus and gone for a larger GTI. The Multiplus is a true hybrid (when configured in a hub-setup), the Axpert is not. The multiplus can do GFPR, the Axpert cannot. I'm not quite sure why you can't coerce the Multiplus to cycle batteries deeper, you can configure that thing to kill your batteries with very little effort. Oh well though, water under the bridge. I would also love to get this one, but I'd have to sell my smaller 24V Multiplus first, and even if I get what I paid for it, I'd be 13k short... :-)

We had it on invert priority, i.e. solar only charging batteries with AC doing maintenance charges; and the one thing I can say about the Victron it is very causes to drain your batteries if it knows your PV is on the short side as it does all sorts of calcs taking into account daytime consumption vs solar power etc.

There was a bloke here in Cape Town (he's also on youtube, mjlorton) who had a hub-2 setup, configured to drain the batteries up to a certain point. In his one video he explained how he set the time period for battery voltage to 7 minutes because that's how long it took to cook a kettle in the mornings... :-)

In other words, I'm sure you could have solved that problem with a bit of programming.
