I'm about to expand my system from 1x Multiplus 24/3000/70-16 to 2x units in parallel, so I can have more inverter power. Currently, overload warnings/alarms come between 1800 ~2200 W depending on temperature.
I would like to ask community what are the important points to observe. I have read the manual, but is seems more focused in 3 -phase systems.
Things that I already had in consideration:
1. Ordered an unit that has similar hardware characteristics, informed that it was to match current unit
2. Ordered an MK3 so I can update my current Multi to same firmware version.
3. I will arrange a DC bus bar so both Multipluses see the same voltage from DC in
4. I will arrange an AC board so both Multipluses have same input and output AC wires lenght
5. Now my question: my current Muliplus is controlled remotely by the Venus, changing from GRID to Solar according with my needs. The Venus relay is physically connected to AUX1 of Multiplus, and I have programmed General Flag and Programmable Relay assistants to current Multi so I can change the operation mode (charger or inverter). Will I need to wire also the second Multiplus? I think so, but just to be sure. Any problem about this? Will they switch at same time?
Any other advice?
