1. Product Introduction
1.1 Product Overview
This product can keep monitoring the solar panel's generating power and tracking the
highest voltage and current values (VI) in real time, enabling the system to charge the
battery in maximum power. It's designed to be used in off-grid solar photovoltaic
systems to coordinate operation of the solar panel, battery and load, functioning as the
core control unit in off-grid photovoltaic systems.
This product features an LCD screen which can dynamically display the operating
status, operating parameters, controller logs, control parameters, etc. Users can
conveniently check parameters by the keys, and modify control parameters to cater to
different system requirements.
The controller utilizes standard Modbus communication protocol, making it easy for
users to check and modify system parameters on their own. Besides, by providing free
monitoring software, we give users the maximum convenience to satisfy their varied
needs for remote monitoring.
With comprehensive electronic fault self-detecting functions and powerful electronic
protection functions built inside the controller, component damage caused by
installation errors or system failures can be avoided to the greatest extent possible.
1.2 Product Features
◆With the advanced dual-peak or multi-peak tracking technology, when the solar panel
is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the
controller is still able to accurately track the maximum power point.
◆A built-in maximum power point tracking algorithm can significantly improve the
energy utilization efficiency of photovoltaic systems, and raise the charging efficiency
by 15% to 20% compared with the conventional PWM method.
◆A combination of multiple tracking algorithms enables accurate tracking of the
