For a few years we have been using a solar array, charging a BYD lithium battery box, running through an Easy Solar 48/3000/50 Multiplus.
Finally, my hydro system is ready for adding in to the existing system for the winter months, when there is less sun and plenty of water.
I was excited the other day when I got the power from my F&P washing machine motor pelton-driven generator up to just over 500W. Still not up to the calculated 1000W I'm expecting...
I had just reconfigured my water system to be more efficient. In hindsight, I should have re-measured the no-load generator output voltage again, as it had probably increased.
I limited the amps in the 250/60 controller to 10A, which allowed the pelton to spin at higher revs, higher voltage. Half a kilowatt was a lot better than the 35W I had been getting previously.
While it was running, I opened the bluetooth Victron Connect app for the 250/60 and changed a few settings. I selected Lithium Iron battery in the battery type, and as it was running at around 200V and 2.6A, I lowered the maximum amps to 5A. Suddenly, the turbine must have been unloaded, as the volts hit 260v and the system switched the load off.
The result was the entire system went down, including the BYD lithium battery box. Up and running again half an hour later, thankfully.
My question: Why did the system crash? Was it by choosing lithium battery as battery type for the 250/60 charge controller? Or was it by limiting the charging amps to 5A? If so, why would this make a difference, if it was only running 2.6A in the cable?
