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

There are a few considerations here, such as can the batteries take more charge than what the multi gives without being damaged? Is this a single unit system? A BMV would be able to measure the SOC for you as it counts energy in and out of the battery bank.

Yes the batterys are 840Ah at 18s. They can take 1c (so nearly 50kw).

yes it is single phase with only one MP II 48/5000.

The 5kw load is more than needed but the charging power (20kw Solar Generators) could be higer.


the System also has ccgx and EM-24 so will the BMV integrate in ccgx?

You can add a separate battery charger, yes. If you want accurate battery monitoring in that case, you'll need a measuring device like BMV-712 or SmartShunt at the battery terminal.

Hi ben,


adding a shunt would be a great solution.

is it possible to integrate a shunt in the Battery Monitoring of Multiplus II or maybe the ccgx? Is it maybe possible to use https://www.victronenergy.de/accessories/current-transformer-for-multiplus-ii#pd-nav-image

this to messure the additional charging power?
