MultiPlus 3000 and 5000 in parallel?

I am currently running a MultiPlus 24/3000, single phase 220 for domestic off grid power here in Spain and was recently gifted a still functioning MultiPlus 24/5000. Is it possible to connect both these units with their outputs in parallel to gain capacity? If so, is there a resource manual available for their setup?

@Patrick Kelly NO... to connect victron inverters in parallel... they MUST both be the same inverter.
they would both need to be 24/3000 or both 24/5000

the only way to do it with differant invertors is to cascade them
I have a main system, a pair of MP II 48/5000 and then I have a smaller cascading system a 48/1600
it uses MQTT to control the 'grid set point' of the smaller one..
when the main system is charging, the smaller one charges, and when the main system is discharging, the smaller one discharges

my main battery is 16kWh and the smaller one is 5kWh... so I charge/discharge the smaller one at 25% of the main one... and it works well
