I have a mp1 5000/48 and a mp2 5000/48, is it possible to run both in parallel on on battery, or at least to use the mp1 to increase the battery charging power?
asked
how can multiplus 1 be used as charger in combination with a multiplus 2 as master and one gx?
Hi @gnagflow
It is not possible to parallel different model inverters and synchronise the AC outputs. for more information:

It -is- possible to increase charging power with an extra inverter, or use the other unit with seperate AC output, but please make sure you know what you're doing to build a well working system. There are also other limitations (e.g. on the VE.bus if there is a GX device as well, or depending on the type of batteries, managed or not, etc. etc.)
Thank you for your quick answer! Are there any information sources how to configure the mp1 only as Charger with one gx. Reason is, I have about 5.5 kw pv power and can only charge about 3.5kw with the mp2 5000va into my 40kwh battery bank.
Thank you!
Hi @gnagflow
if connected to the output, you'll have to split up your solar power in order to adhere to the 1:1 rule.
Hi Daniel, I dont see a problem with the 1:1 rule. I only have an 5kW inverter with oversized panels and the 5000VA multiplus 2. Excess power is backfeeded to the grid. The question remains. How can I use another MP1 5000VA only as a charger to increase charging power up to 5kW?
thank you for your help!
I use an external bms and control Charger/inverter with two signals.
