Also, how do I get in the victron windows based page.
I’m only currently on victron connect ?
You may be better off downloading the VE-bus tools from
https://www.victronenergy.com/Executables/VEConfig/VECSetup_B.exe
This makes it easy to check the inverter configuration and access the logs.
you can update the inverter firmware from Connect, just click update device and follow the steps.
You can also use VE configure on a laptop to monitor the generator volt & frequency while it is connected, or trying to connect. The VE-configure tool also allows you to configure the max generator current and battery charge current.
Please, read this…

Ok great.
I’ve got the config tool on my computer.
I’ve set the config 3 to weak ac input to see if it helps.
I’m a bit nervous about the inverter update, not really that confident in I know what I’m doing?
I’m ok with the 1st stage, it’s just the last part that troubles me.
If it goes pear shaped, I’ll have no power.
Hi @TheNook ,
Coincidently, similar issues here with a recently purchased Hyundai DHY6000SE - purchased around the start of February 2025.
With a Multiplus 12/3000/120 - @2100W the generator input is relatively stable. Generally with no other AC loads, 100A@12V charging is reliable, but adding other resistive loads (e.g. 800W water heater), it becomes tends to become unreliable and intermittently disconnects, especially with variable fluctuating loads (e.g. microwave turning off) even with a higher input current limit. Sometimes I have noticed that the behaviour depends on the ambient conditions. For example, at cold temperatures recently around 3-5 degC, the stability of relay switching is more erratic until the generator has warmed up after 30 minutes. Ensure that you give the generator a 5 minute warm up-time as recommend in the manual.
WeakAC option may work to some degree, but you limit your max charge by (20%). However, after reading several reports across this forum and website, it is my suspicion the quality of the waveform is simply not good enough at higher loads (>2kW). The other recommendations people have posted is ensuring use of good wiring and connectors to the generator to prevent ‘dry-joint’.
Other recommendations are disabling (UPS) and dynamic current limiting if you don’t have sensitive equipment. See this further blog post (Understanding an AC Diesel Generator - The Sumpners Afloat)
These I will try soon at some-point soon. However, confirming the errors via the diagnositc logs in VE.Configure will be helpful identify the cause of issue.
