Action for customers
This can be due to several reasons:
There is no DC power connected to the Elon Smart Water
DC power is off at the DC disconnect switch located near the Elon Smart unit.
There is an issue with the DC wiring or solar PV installation.
It is extremely dark and overcast during daytime (The alarm is not active when the sun is less than 15 degrees above the horizon).
This alarm won’t prevent the Elon Smart unit from functioning and heating water
with grid (AC) power as long as there is grid power available.
You can clear the alarm by:
Switching the DC power on (where applicable).
Setting the Elon Smart heating policy to Grid Only.
Leaving it until DC power returns.
Contacting your installer or electrician to inspect and fix the DC wiring and/or solar PV installation.
