I have 3 inverters installed in parallel which supplies a house with 2 outbuilding....3 geysers ...entertainment area ...pool pumps etc.
All connected to a 60 amp single phase supply.
Here's the challenge ...geysers ...pool pumps and other non essential supplies... they drain the batteries too quickly.
I need a solution to this problem... i could run control wires to each device and fit a contactor or relay ...the problem is the distance and access to the various locations...something like the old ripple relay system the municipality used back in the day.
The other thought was to fit wireless unit ...like a sonoff ...a receiver...wifi unit or even bluetooth to control the device when the power turns off.
It sounds simple however ...each item is fed via a sub DB with a pre paid meter which has other stuff like fridges etc.
What i am looking for a simple wireless solution to control these devices without having to separate them from the sub DB they are connected... there was an attempt to separate them via the main DB ...however this no longer works because the sub DBs now have prepaid meters.
Power goes off...a signal is sent to all the devices to shut down and when the power is back on... a delay staggering the power on to each device ...preventing a heavy load on the system.
