We have used Gigavac in some of our Li-ion EMS systems for many years with hundreds in the field and no failures. GX11 good to 800Vdc. https://www.gigavac.com/catalog/power-products/gx-series

A little background: Per Sonnen Batterie tech support’s recommendation I have installed a 10 kW SolarEdge HD Wave inventer coupled with the Sonnen Eco 12. Although the Sonnen Eco 12 uses an Outback Radian 8kW multimode inverter(of which Outback suggests to max AC couple input of 5kW) Sonnen says that AC PV input greater than 8kW will require a contactor to interrupt a string or two of the grid interactive inverter so that it’s output will remain less than the max 8kW input. That’s fine and well, but when asked directly, Sonnen didn’t have a part # for the contactor and suggested that anything over 150V DC would be difficult to find. Anyone know of a 600V rated contactor that would suit the bill? Essentially the contactor would need to sense grid interruption (via a 15A-AC breaker) and open a 600 V rated DC string. I’ve done some preliminary searching and have come up empty handed. Any input would be greatly appreciated. Best, Chris -- Chris Sparadeo C_802-369-4458 H_802-728-3059
