I need to see if you guys know if a product exists.
What I would like to do is add a fail safe mechanism to a water well PV system.
It will be a basic dedicated off grid system:
Grundfos well pump 230V (the pump is the only load at 1400-1500W except maybe a light in the well house).
3 200W solar panels
4 golf cart batteries (24V system)
MPPT controller (currently looking at VICTRON SMARTSOLAR 75/15 MPPT CHARGE CONTROLLER)
Still looking at inverter options. This one is challenging since the pump is 230V. I have a 2000W transformer, but I'm afraid it will be too parasitic.
Charge controllers and Inverters have the ability to protect batteries with a low voltage cutoff. I hope to have this ability with both components, but I would like to add another layer.
If there happened to be a break in the water line, it would gush water until one of the components tripped the LVC.
Is there a timer device that can disconnect either the inverter or the batteries if the current has been flowing for more than a few minutes (adjustable)?
I do not use prolonged watering of any kind, so there should not be any constant operation of the well pump. The pump only takes about 15-30 seconds to fill the tank and shut off. I would like a device that will interrupt the system if it is drawing current for more than a few minutes, and require a manual reset to resume operation to protect batteries, save water, and prevent water damage.
Know of any such device?
