Hello everyone
I’d like to build a solar + inverter + battery for my home, but I’d like to build it with one inverter (one-phase) first and expand to 3 phases later due to budget constrains.
I checked with gpt and it suggests the following way:
Start with MultiPlus-II GX 6K5 and later expand by adding 2x MultiPlus-II 6K5 (non-GX)
Quesiton: is it a viable way, to start with anoter dvice, paticularly EasySolar-II GX 5kVA and then expand by adding 2x MultiPlus-II 6K5 (non-GX)? Would they be compatibe and able to work in one 3-phase system ?
ps. more on my starting conditions
I have a 3 phase grid entering my house which is 3 x 5 kW (25 amps) 230 V
I will build at least 32 kW battery (maybe more later, and as well expand gradually)
I have EV with a 24kWh battery and I charge it with standard 1 phase 230 V and it’s Okay for me (even despite 9 h full charge time), but I want to replace this car to a newer 50-100 kWh at some point and I will want to charge it based on 3 phase charger then.
It makes sense to start with a MultiPlus2, particularly the new 4k5 or 6k5 models, as these will probably remain available in this version for longer.
As far as I know, it’s not possible to combine a MultiRS with a MultiPlus2.
Go for an MP2 and choose the size according to your needs, but it’s better to go slightly larger rather than smaller—especially as you’re planning quite a large battery anyway, and your electricity consumption is likely to increase in the future.
For the PV system, if possible, it’s advisable to build part of it as a DC charger and integrate any additional systems via AC. That way, you get the advantages of both worlds.
Jetlag, thank you man. im not knowledgeble yet about “integrate any additional systems via AC” but I will explore , thank you for pointing out. I am thinking of various scenarious for extra pv energy dump into misc applications, which is a huge topic for me as I like diy

Thank you, yes, I thought of it, but I am going to keep stuff inside and I think I am going to be much more comfortable with heavy thoroidal transformer’s humming sound than with high frequency rotating fans of Multi RS Solar in sunny days.
