Install and Operation of the SUNGOLD 10KW 48V SPLIT PHASE SOLAR INVERTER

APL mode not wanting PV power. If someone has an idea... please share

Interesting. I run mine in APL mode for 3 or 4 months now, and when the battery is full, it still takes just enough pv to satisfy the load. In other words, I did not observe what you quote from the manual.
I have the 10kW version.

Did you actually observe this or is this just from the manual?

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 luck. I turned off grid and it kept supplying the load with PV and batt no problem. I turned off batt and it kept supplying the load (500w at that point), but as soon as I turned grid back on, it went to bypass mode again.

The only way I was able to make it go to hybrid (grid+pv supplying the load and pv excess energy exported to the grid) was to change to UPS mode. After that, PV power jumped from 0 to 7kw therefore supplying the load and exporting the rest to the grid.

I switched to APL days ago with no issues at all.

I know must people dont want to feed excess energy to grid but for me, it works pretty well to lower my bill. That's why I want full PV power all the time and not just to carry the loads.

UPS mode did the opposite after power outages... inverter didn't want to switch from solar+batt only to hybrid even at night, only.a reboot would fix that.

the "export function" is enabled, right? Because by default, it is disabled.

my apologies if you stated this already, it's hard for me to read on this phone right now.
 
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 from APL to UPS but that isnt how it suppose to be and it means I need to be constantly checking.

Understanding how the brain of the inverter works is crucial, the manual does lil to nothing to explain any of it. This thread has been the most usefull so far.
 
I am not aware that any of the experienced posters in this thread have export enabled. It may be a good idea to send an email to support.

I do have a question for you though. When you export, does the inverter export through the AC-output (which I have hooked to a service panel) or through the AC-input?

If through the AC-input, that would mean that this wire is used bi-directional, right? Either for pass-through, or for export.

I read in another thread where a GroWatt inverter was unexpectedly exporting. I wonder if this is a risk for the SRNE (SungoldPower) inverter as well, if I have only a connection from grid into AC-input.

I agree. The manual - which is really just a reference table - raises frequently more questions than answers.

What does setting 34 do when [01] = SbU?
I would like to export maybe 1kW or 2kW, as I have a legitimate permitted grid tied system, it's 5kW but 20 years old and rarely reaches 3kW - of which at most 2kW get exported.
So, adding one kW from the SRNE might be "safe". Then the next question is, how do I limit the export to a certain amount.

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 it back that easily. It happend to me before I was authoriced to connect to the grid and I runned on SOL mode.

As far as I can tell, there is no way you can set a limit to the export on this kind of inverters. Maybe with SA?

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.

@Enzo.R what do you have for setting 5... Default is 57.6 but I don't ever charge my batteries past 55.6... Although that is if 1 is set to SBU, not for UTI...

Also there should be a timeout feature when mains come on or when starting the inverter that will be used to test the stability of the mains. This is normally 3-5 minutes if I remember right.

Argh... Had to order a bigger breaker for my old main panel that supplies power to my new panel when I take the solar offline and the one I ordered is the new stab when I needed the old stab federal Pacific breakers so now I have to wait till Wednesday to get started... Oh well.

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 logic behind, what triggers it is not on the manual. UPS/APL mode and Battery settings need so much more explanation.

I havent found that on the manual but I have seen it takes just seconds to do so.

My guess is that battery settings, if not set correctly, will cause a loop that will mess with the inverter logic.

I need a good old 90's Flowchart!
 
Are you guys all running a single inverter or paralleling 2? I think @Enzo.R is ... When first turning the system on, do you go grid, batteries, inverter breaker, start switch and do the first unit and then setting 31 to PAL and then bring the second inverter online?1000008776.jpg

@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.
