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...
I don't believe it is available for download anywhere. It could be a "beta" firmware. After a few more days, it seems that MPPT algorithm is l...
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
If you manually charge indivitual BOS-G pack you have to charge it up to ~57V max. Each pack is 16S LFP configuration, and max voltage of each cell ...
No you can't. You will need a power supply that is capable of outputting at least 60V to charge individual battery packs.
Funny thing happened a few days ago while testing Deye SUN-XL02-B optimizers.Due to snow cover, one of the Deye optimizers in the string did not wake ...
West - East strings in parallel will work completely fine, as long as you don't have any shading, this is easy task for any MPPT. If you have shadin...
