Hello all,
I have a Multiplus 12 3000 120v, Smart Solar MPPT, Color Control and a Honda EU2200i. The gen can produce 15amps and I have 600 watts of solar. My goal is to charge an electric UTV with the system, initially via the generator and once the power demand drops with the solar.
I can charge my system fine with a 15a current limit with the Honda, but once I plug the UTV in, the Multiplus kicks the generator connection out and in.
When you first plug the UTV charger in (120v cable) the Multiplus begins to feed the UTV power. You can watch the watts climb on the color control, and when it hits 1500 watts, it disconnects the Honda gen (but continues to charge the UTV off of my house battery) and then restarts the Honda feed in 10 or 15 seconds and repeats this cycle over and over.
I've played with all the settings in the Multiplus that I can think of such as weak AC and dynamic current limiter but not having any luck. I don't think it's a problem with the gen as I can charge fine using the current limiter. All components have the latest firmware except for the Multiplus. I don't know if it's at the latest as I can't seem to find that info on the website as it seems to be "for professionals only."
Anyone run into this or have any ideas? Below is an export of my Multiplus settings.
