Take Control of your Out-of-control Charger with 1 of these?

Thanks Tom.

Both input and out voltage are 9-60vdc... the bottom right pic shows the labeled connections.

Could one easily compensate for the peaks by lowering the output even more, or would that possibly make things even worse?

(I think maybe the battery bank's enormous load being well over 40a, when at low soc, would also come into play? If so, I guess that would not be an issue on a not so discharged bank?)

thanks
