@Wessss77 Mine is single too. I bought one parallel to start another project but hasnt arrived yet. I have the manual if you want to look at the configuration options. By the way, I think the SPH10K48SP by Sungold, the SPI-10K-U by many others and the ASF48100U200 by SRNE are all the same.

My 05 is set to 57.6... from what I read in this thread some settings are set by the BMS if on a closed loop. As @42OhmsPA says... better leave it USER and no BMS but I havent done that. Keep an eye that the "brain" of the inverter will change UTI to SBU/SOL or back on occasions. What is the...

34 is used to enable export (ON GRD) or mix PV and Grid to support the load (MIX LOD) only if UTI is set. On all other modes it does nothing, it wont export either. But be aware, I have seen the inverter switch setting 01 to UTI (from SBU or from SOL) on its own and not allowing you to change...

I was blaming the battery charging/discharging cicle for this random behaviour.... til I read something on some other thread about UPS/APL settings. Here I plotted 48h from the moment we had a power interruption til the moment I rebooted the inverter manually (UPS mode all the time). You can see...

I wanted to share the following situation since it is not something that you can read on the manual and I can't find an explanation... maybe firmware update? It applies to ASF48100U200-H inverters and other popular clones. Export function enabled but shouldnt be key to the problem. You can tell...

It exports through the AC Input, it is bidirectional. Setting 34 set to MIX LOAD will use PV and Grid power to carry the loads but NO export allowed. Hard to understand that from the manual.

Yes, export enabled and working (setting 1: UTI mode, and setting 34: On grid.). The setup works 99% of the time except for those 2 situations when it doesnt want to go back to hybrid automatically in UPS or in APL mode. I can make it go back to hybrid manually switching from UPS to APL or...

Ok. So basically inaccurate inverter readings, margin of error is higher the lower you go. Understood.

This morning the sun was shining and my PV output was near 0. I went to check and inverter was in bypass mode (no PV no Batt supplying the load). You would expect bypass mode in case of a) inverter overload of some kind or b) batt undervoltage and PV not available. I rebooted the system with no...

Help me out to understand that. The log shows active power of the load a bit below 500w, but Solar total panel power 50-100w. No grid no batt. How that works??

Learnings from APL and UPS mode aside of what is written in the manual: UPS mode: the inverter will not connect back to the grid (hybrid) after a power outage, supposedly bc grid power is "dirty" however rebooting the inverter will reconnect with no problem. PV and batt will keep the loads...

So, grid is disconnected, battery is turned off and both PV arrays show 0A and around 470v.... where is the energy coming from to support the load? It is a sunny day and both PV arrays show good V but 0A.

Here you'll get the link. I recommend reading the thread. https://diysolarforum.com/threads/srne-solar-station-monitor.53551/post-848290

Hi all! Special thanks to @Kenny_ for starting this log. I have read all 94 pages today, arrived a lil late to the party but had the same issues you all had and learned a lot. My set up: SPI-10K-U (same as ASF48100U200-H) paired with 20 Canadian 560W panels and 51.2V 100Ah LifePO4 batt . Happy...
