Features
|
|
 Parallel
Switching Shunt
When the maximum charging voltage at a given
temperature is reached, the parallel switch (U.S. Patent
#4661758) automatically shunts the solar array to prevent
overcharging the batteries.
|
Temperature
Compensation
To extend battery life and prevent stratification, these
regulators automatically adjust for the temperature
of the batteries. |
|
Durable
Construction
Specifically designed for developing nations and sustainable
development projects, ETA controllers are extremely
rugged. ETA mounts the regulator's circuit board in
an anodized aluminum heat sink and then encapsulates
it in an epoxy-resin. This ensures that the regulator
circuitry is protected from the environment.
|
Pulse
Width Modulation
Automatically adjusting to the load requirements, battery
state of charge, and battery age, Pulse Width Modulation
(PWM) brings the battery up to maximum charge without
trickle charging. This design maximizes battery life and
continuously adjusts to the battery requirements as opposed
to 3-stage charging. |
|
Overload
& Transient Surge Protection
All regulators provide an overload rating of twice the
specified input current for 20 seconds to accommodate
the "edge of cloud effect". Solid state transient absorbing
avalanche diodes protect the charge controller from
lightning induced surges and inductive load spikes.
|
Solid State Electronics
ETA Engineering's solar charge controllers have no moving
parts that can fail. To ensure safety, ETA excludes the
use of mercury switches from all of our regulator designs.
|
High Reliability
These designs use High Safety Factors to minimize stress
on all critical components, which gives exceptional life.
Products using this design installed in the late 1980's
are still going strong. |
High Efficiency
The regulators contain blocking diodes chosen for minimum
forward voltage drop which maximizes charging current
from the PV module(s). The static current draw is only
about 2 milliamps plus the current to drive any LED that
may be on. |
