Alarm message
How to resolve the alarm
DC Wired to AC Input
No Power on DC Input
Wire DC to correct input (see Chapter 4).
This can be due to several reasons:
a. There is no DC power connected to the Elon Smart
b. DC power is off at the DC disconnect switch close by
the Elon Smart unit.
c. There is an issue with the DC wiring or solar PV
installation.
d. 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), fixing the DC wiring / solar PV
installation, setting the Elon Smart heating policy to Grid
Only (see Table 4.1) or you can leave it until DC power
returns.

DC Input Reversed
Hot Connection
The wiring on the Solar input has been installed
incorrectly (in reverse). The DC+ (positive) wire has been
connected to the DC- (negative) terminal on the Elon
Smart and the DC- (negative) wire has been connected to
the DC+ (positive) terminal on the Elon Smart. Swap the
DC wires around (see Chapter 4).
Elon Smart not correctly inserted into geyser element.
Switch off all power to the Elon Smart and re-seat
(reinsert) the Elon Smart.
