Can I overshoot Voltage on a Blue Solar Charger just a little?

Q&A and troubleshooting

Blue Solar Charger 150/35.

How tolerant are those devices to overvoltage?

What if a string hits 160V on rare occasions?

My panels have shortcurcuit voltage of 38.88V

I add 10% (-0.25%/C°) for temp compensation.

At the moment I have a string with 3 such Panels.

I wonder if the charger could handle a fourth also… if there is tolerances..

Anyone got any experience with this?

No experience but in the old forum, @guystewart indicated that voltage is a hard limit, unlike current which you can overshoot a little. He didn’t say what that does to your warranty.

That’s definitely a hard no - voltage limit is not to be exceeded under any circumstances.
