4.2.2 SunFlo-A
Pumps are controlled by an internal motor controller with no external monitoring or
adjustment provisions. However, pumps must be connected through the PV Isolator that
also provides over-current protection.
4.2.3 SunFlo-B
All SunFlo-B pumps are provided with an advanced MPPT controller that enhances pump
performance by up to 25%. The controller includes an isolator switch, protection from
over/under voltage, overcurrent, low level control (optional), indicator lights for pump
operating status and provision for high level floatswitch.
