From all suppliers, they have the best prices.

Am just not sure if all the branches have the skillsets to support / repair Victron kits, as they are rather big.

Who has been shopping for a 48/5000w version of the multiplus  II and where was the best price . I found a current automation for just over R22K .

Do they have stock yet and which one did you contact?

I estimated the other day, based on the price of the 3KVA and the Euro price ratio that it should be around 18k. But it really depends on many other factors too, the smaller units benefit from popularity (larger volumes). 22k does not sound completely ridiculous.

If it is anything like the 48V/3kVA Multiplus-II, they will go through the following "phases".

  1. New product, not yet available
  2. New product, has to be ordered in at premium price (xxx weeks delivery)
  3. Stock available, now at reasonable price
  4. Victron introduce a special promotion and price drops even more to boost sales

Step 4 normally happens just after you purchase your unit 😆

What size are the battery cable studs on the Multiplus II? And are the nuts included in the packaging?

They are in fact m6.  And do include all washers and nuts required .

Usually what happens is they find a way to produce the more popular models cheaper and faster and then some of the savings are passed on to the customer.

Thanks for all the replies. Unfortunately, a cold took hold of me, so I wasn't able to do any of the work I wanted to do.

Since I couldn't do any physical work, I spent time reading. I came across the following on page 9 of the Multiplus II manual (old manual):

"The AC input must be protected by a fuse or magnetic circuit breaker rated at 32A or less".

The commonly used CB's are usually thermal or thermal-magnetic. Why do they explicitly state that it needs to be a magnetic CB?

Probably just to ensure that people do use a breaker that has a magnetic component. Not that I have been able to find a breaker that DOESN'T have this...

Thermal-magnetic is perfectly fine. The magnetic part gives you an instantaneous trip on large overcurrent events (10 times I_n or more), while the thermal part trips on smaller overloads over longer periods (eg 10% over might take several minutes to trip).

Nice. I hope your install goes quicker than mine!

Lined up for next week. Luckily I bought batteries already, panels don't seem to be an issue, should arrive tomorrow.

I've had my 3000VA MP II and US3000 Pylontech since March. Thus far I have managed to hang the inverter and the new DB.

I'm installing as a UPS at the moment, so no solar. But what is taking time is the fact that the DB where the inverter and essential loads will be wired into are physically separated from the main DB. Therefore I need to do some re-wiring of the house to get everything working.
