[Solved] Honda eu10i not syncing to multiplus (revised: no generator syncing)

Hello,


I have hooked up a new Honda eu10i generator to an EasySolar 3000. The CCGX identifies the generator is there, but will not accept any charge. It attempts to sync with a click, but disconnects instantly. Current limit is set to 5A, but it doesn't even get that far to load the generator.



I have tried all of the settings in the generator faq; weak ac, UPS disabled, etc.. but have not had any luck.


Current non working config is attached;

Any help would be great!


Thanks,

Zooka.

I finally got around to getting this fixed. It was a problem with the EasySolar unit itself. In the end the unit was not even clicking - the sound of the relay engaging to admit power to charge the batteries. The relay itself was faulty and repaired under warranty. Both generators work perfectly. Yay!


Thanks for everyone's assistance.

Hi Zooka. That's a very small genny, and your 5A limit is an ac limit, so likely way too high for it. Inverter gennies take-no-prisoners if they're overloaded, and won't deliver.

Set (say) a limit of 2A for testing, but you can easily(must?) do that in the CCGX, the setting there should override the Multi limit you've used in VEConfig.

Note there's a lower limit in your 3000 that it's possible to go to, and without looking it up, you may come across it at the 2A level.

Have a go, and we can work from there.. Good luck.

Also with the VE config under general turn on dynamic current limiter

this will SLOWLY increase the load to the generator

this may help but follow JohnC advise first

Yeh, this link actually highlights the 'Overruled by remote' tickbox. So then the CCGX rulez for sure. Easiest way to fool with trial settings..

Thank you @PaulB and @JohnC for your responses.


I have dynamic current already enabled. I set the lowest setting available which is 4.5A, unfortunately it won't allow 2A. I pulled out my no name 2.4k generator and it is doing the same thing. Just won't sync up.


With the 2.4k genie;



Limit set to 4.5A;


And AC1 set to generator;


If there was a problem with the wiring you think it wouldn't detect the generator at all? (edit: I wired a plug straight from the genie to the multiplus to eliminate any issues, same thing happens.)


Any further ideas?


Thanks,

Zooka.

Here?



Tried 20 and 10A, no luck. Also tried turning off PowerAssist, same result. This is still with the 2.4k genie.

Hello Zooka,

I have just updated the Multiplus Generator FAQ since your post, specifically the last section on PowerAssist.

Please run through it again.

Hey Guy,


I disabled PowerAssist and was able to drop the current limit to 2A, still no luck. Testing with Charger Only mode was also unsuccessful. I even tried disabling ground relay.


At this point I am going to assume this is a wiring issue that is above my level of expertise, but shouldn't running in Charger Only mode disqualify anything wrong on the AC out line?

Have you got the grid code set to

None as per below "This is the inverters default setting"

I have seen this happen if you have a different grid code setting.

as the generator gets a power back-feed of some type or the inverter does not like the connection as it cant export power or some thing like that.

Also looking at your inverter file I see the firmware is 413 try upgrading it to 433.


worth a try
