I need to extend my solar-system with more panels. This means, that my existing MP GX 3000 can't handle the power to the net any more. So I want to extend the system as ESS at L2 with a MP 5000 GX.
Is the combination MP3x and MP5x possible, or do I have to exchange the exxisting 3kW one for a 5kW one?
No you cannot mix a 3k with a 5k. They need to be the same model and as close to the same production date as possible. You can however parallel a gx unit with a non gx unit, but they have to be the same size.
Thanks Derrick,
will change the multiplus itself to a bigger one
