Maximum power pass through possible on Multiplus II 32A?

what is the maximum power that can go through the "Critical Charges" in multiplus II?

I know that without the presence of the network I can only inject with the inverter 2400w.

Basically I wanted to know if it's possible to "load" the whole house (32A) into ACin

Explaining .... if you have contracted from network 32A of the network,

can I pass this entire chain through the multiplus II before entering the house distribution board?

Multiplus-II
2 |3000

Up to 8 attachments (including images) can be used with a maximum of 190.8 MiB each and 286.6 MiB total.

The specific specification I think you are asking about is the AC input current limit, or AC transfer switch limit. This is available in the data sheets for each product.

For the current Multiplus-II, the AC input current limit/AC transfer switch limit is 32A. Though this is the LIMIT, so it is best to leave yourself some additional room in the design.

So yes, you can load the whole house through the AC-Out 1, and the grid will support it.

However why not use as intended, with the essential loads (fridge, lights, communications) on the AC-Out 1, and leave the big loads on the AC-Out 2. This will mean the inverter will not overload when the network is unavailable, but will support when it can.

Would there be an advantage, at this level, in the previous multiplus of 3000 in the 50A version of transfer? and a multiplus 5000? or does this latter multiplus II have other advantages besides the disin?

In the event of a grid failure, could one way of increasing the number of essential loads in AC-1 be, for example, add a grid tie inverter I already have (fronius ig30) in AC-1 to increase the maximum 2400w of multiplus-II? To do this, I placed my meter imerssun next to AC-1 to divert the amount that might exist when the batteries are fully charged by the II

Hi Guy,

What is the maximum inverter output in Watts of the Multiplus-II for 1 minute (overload) assuming 24 degrees with fan-forced cooling? Note our mains will be connected and current limited to 10 A 230 V/AC. 2x LiHE 100 Ah will be connected with Lynx Ion 1000A BMS. No solar or generator will be connected.

Thanks Mark

Hi Mark,

Please ask in a new question. I am sure others would also be interested in finding that info.
