Rated input voltage
250V AC, 240V DC
Rated input current
25A AC, 20A DC
Mains (AC) voltage range
-50% to +100% (but will disconnect all loads when breach is greater
than +/- 15%)
System power supply
Solar or 230V AC mains
Power consumption
<3W on mains power; <0.5W on solar power
Shutdown
Sufficient power supply capacity to manage processor, switching and
data storage if both mains and solar supply fail
Solar voltage (V
oc
at STC)
20 – 250 V DC
Solar energy availability
Automatically determines availability of sufficient solar energy
before supplying load from solar modules
Controller settings
Can be adjusted to run from “solar only” (100% solar energy use) to
"mains only" (no solar energy use)
Thermostat
Uses the standard normally open thermostat switch associated with
the geyser element as a sensor only, with less than 10mA sense
current, to control power to the element
Reverse polarity protection
Protected against reverse connection of solar array
Enclosure ingress
protection rating
IP65
Maximum distance Elon®
unit to controller
10 m
Annual energy production
compared to inverter-
based system
> 90% when solar array and geyser element are matched correctly
Standards conformance
IEC / SANS 60669, CISPR 11 & IEC 61000-6-1
Dimensions & weight
Elon® 100 main unit: 200 x 150 x 60 mm (LxWxH), 1.75 kg. Controller:
50 x 72 x 41 mm (LxWxH)
Patents
ZA 2019/02129 (pending), GB2583814A (granted),
PCT/IB2021/050542 (pending)
It is important to match modules and heating elements for maximum power transfer efficiency. See
the tables in Appendix D for the recommended heating element power rating for different solar
module specifications and array configurations.
