I’m setting up my multiplus 12/3000-240v to assist my small 2.1Kva generator during peak loads. I understand that the input current limit is actually 10% lower than the set limit so when set to 8A assist starts at 7.2A. And that there is a minimum assist level of 1.6A for this multiplus model. so…

[image] bigbadbob76: how much load do I need to shed in order to drop out of assist. It should be any time the load drops back down under the 8 amp set. Theres a few slight variations… If you have dynamic current limit on it can also affect it a bit. So a few amps different. It also has a b…

Thanks for your reply LX. There appears to be some hysteresis so it has to drop somewhat below the 8A set current before it drops out of assist. This makes sense as it prevents the system flip-flopping between assist and no assist when the power draw is around the set limit. The “somewhat below” …

The somewhat is affected by install and load so i guess that a voyage of discovery you are on…

@bigbadbob76 this is an interesting concept because switching in and out of assist doesn’t strike me as a big problem. I wonder could you outline the reason for the enquiry as for me, the assist function is a linear application of the feature. For instance, if the setpoint for assist is let’s say…

AC input current limit. Set this to a safe value for your generator so the inverter doesn’t let the generator run overload. Dynamic current limiter if enabled, the MultiPlus will gradually allow the generator to supply more power; useful for small or slow-ramp gensets. Assist Current Boost Factor s…

Thanks guys. Trevor- yes, an interesting concept, according to the spreadsheet on Victron pro my multi has a minimum assist level of 1.6A so when you go over the set point by say 0.1A it assists with 1.6A not 0.1A, so the current draw from the generator drops by 1.5A. the drop takes the generator …

There is another thread that describes the threshold trigger a bit more form the spreadsheet.
