MPPT
(
Flashing Green
): The MPPT (Maximum Power Point Tracking) monitors the power input from
the solar panels and adjusts the voltage and current to gain the highest performance of the pump.
This indicator light will flash green when the MPPT is working properly.
ERR_1
(
Solid Red
): This light will usually illuminate when there is an overcurrent issue. If the pump
is drawing too high of an amperage, the overcurrent protection will engage to protect the pump,
motor, and controller. The pump will be shut down until the system is reset. It should automatically
start after 20 minutes. If not, cycle the power switch and verify the
ERR-
1 light has turned off. If it
repeats, call Technical Support. Overcurrent can be caused by pump or motor problems, shorts in the
wiring, or even a blockage in the piping. Please consult your Authorized SunRotor
®
Dealer for
technical support, or contact SunRotor

Technical Services Team directly at 1(866) 246-7652.
LOW POWER
(
Solid Orange
): This indicator light will illuminate when there is not enough power to
operate the pump or when the pump motor cannot start because of blockage, torn stator, or other
factors. Low sunlight or hazy conditions are usually the cause.
Tank_F
(
Solid Red
): This light indicates the storage tank is full. When water in the tank reaches its
desired level, the float switch rises and closes the circuit. The pump will shut down until the water
level decreases and the remote switch returns back to the open position.
Well_L
(
Solid or flashing Red
): This indicator light is illuminated when the water level in the water
source has dropped below the sensor. When the low water sensor is tripped, the pump is shut down,
and the timer will start as long if it has been set above zero (red light flashes when timing). The
pump will restart when this time expires. The time is adjustable between 0 and 30 minutes.

The purpose of a float switch is to turn the pump off when the storage tank fills, and to turn it back
on after the level drops again. The use of a float switch is highly recommended to reduce the running
time and to prevent waste of ground water. It can control the pump from a long distance away as
long as the proper wire is used. Ask your Authorized SunRotor
®
Dealer about pricing and
applications for float switches.

solar pump systems require a minimum of 10 gauge pump cable, except when the
TDH is greater than 300 ft., in which 8 gauge pump cable is required. It is also recommended that
any and all additional instrument cable not provided with purchased sensors and float switches be a
minimum of 18 gauge shield twisted-pair cable. This will help prevent damage from ambient or
transient lightning strikes. If unsure of the proper wire sizing, contact your Authorized SunRotor
®
Dealer or the SunRotor
