Sinotimer SVP-916 63A adjustable voltage protector

[@saniupplomberietoulouse5082]

I just installed it following a surge in the electrical network (250 volts) which damaged the boiler's printed circuit. I set p01 to 230 volts and p02 to 225 volts but I still have 250 volts supplying my boiler

How to reset to factory settings??

[@Swenser]

Im using this after an inverter in solar system but think it's tripping or resetting often . Maybe doesn't like the sinewave shape.

[@CNCTinker]

do you also have batteries ? otherwise the output will fluctuate with the solar input. if you do maybe the inverter its not too good quality and still fluctuates. or maybe its a square wave and might have higher rms compared to a sine, try to increase a bit the tripping limits.

can you tell me if it keeps its settings if the power goes out?

[@CNCTinker]

yes it keeps them, I kept it unpowered for one day to make sure before mounting it. it has a microcontroller that checks the voltage and data saved in the flash memory remains there even when power is removed. its same flash memory like on a usb drive just only a few kb.

how to set the device to be at 63A ?

[@CNCTinker]

you can set it in the menu to trigger between 1 and 63 amps, though I wouldn't recommend to use this above 40 amps, as its not a well known brand and at that much current you risk to set something on fire

How to reset to factory settings??

[@CNCTinker]

Press arrow up + arrow down together for 3 seconds, and the LED will be off for 1 second, indicating that the default parameter value of restoring factory settings is completed
