Good Day,
I currently have a 24V 3000W Multiplus with an MPPT and 2 batteries. My loads are growing greater that 3000W will adding another 3000W Multiplus simply increase the Kva or is the a lot more that needs to be considered?
Regards

Can I just add another Victron Multiplus 24v 3000w in parallel to increase power?
You have to program them to work together in parallel using "VE.Bus Quick Configure" (included in the VE.Config software package).
Hi @Denzel,
There are a few things to consider.
The units must be the same model firmware model number (first 4 digits, eg 2641) and depending on the age of your other unit, the same may not be available, so it may not be possible.
There are also important designs considerations such as perfectly balanced AC and DC wiring. This may be easy or difficult depending on your specific installation.
You must also be very careful with communications cables, and maintaining a continuous negative connection so as not to damage the communications cards.
There are more, and there is some detail in this manual: https://www.victronenergy.com/live/ve.bus:manual_parallel_and_three_phase_systems
It's strongly advised to see the help and support of someone who has experience and a good track record of success: https://www.victronenergy.com/where-to-buy
Lastly, a warning; if your batteries are not designed to deliver the additional current demanded, you may not get any extra useful power, and could even do damage to your system.
Do/will you have any single 3000W+ load in the future scenario? If you don't, you also have the option of running the 2nd one independently. Just make sure that there is no possibility of cross connection by the loads or in your wiring.
