XL02-A is just an optimizer, XL02-B is optimizer with monitoring and fire safety. XL02-B needs concentrator unit for communication and "shutdown" fu...
You are underestimating the influence that string orientation has on the production especially in winter months with low sun angle. For your S/W...
No, you should never connect the MPPTs in parallel.
This is probably the latest available Modbus protocol document... v105.3. It should cover all 3phase LV and HV inverters. SUN-15-20k-SG05LP3 line ...
Most probably it does nothing. Because it is just a option in display firmware, but not linked to anything on the main inverter firmware. You can te...
With just 7 modules in series your voltages will be very low. That will reduce performance especially in low light conditions, inverter will start t...
Optimizers will not run optimally without some sort of "global MPPT scan" or "shadow management". I had optimizers installed on my strings before th...
Ask Deye to install firmware "F150" on your inverter. I have it on mine since 2 weeks, and MPPT behavior is much better than before. With this f...

I contacted Deye support because of the MPPT issue that I noticed on my system under shading conditions. Old FW never dropped MPPT voltage below 70%...
Yes, that is normal.
So there are some new options available in the "F150" firmware for 3-phase LV inverters. I can set MPPT_scan ON or OFF in the Advanced settings 3 ...
Anybody seen this version yet on a SUN-12k-SG04LP3-EU? Updated today by Deye

No you can't. You will need a power supply that is capable of outputting at least 60V to charge individual battery packs.
