Product Overview

•  With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails to result in 
multiple peaks on the I-V curve, the controller is still able to accurately track the maximum PowerPoint. 
• 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 optimum working point on the I-V curve in an extremely short time.
• The product boasts an optimum MPPT tracking efficiency of up to 99.9%. 
• Advanced digital power supply technologies r aise the circuit's energy conversion efficiency to as high as 98%. 
• Charging program options are available for different types of batteries including gel batteries, sealed batteries, open batteries, lithium batteries, etc.
• The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is 
larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level. 
• Instantaneous large current startup of capacitive loads is supported.
• Automatic recognition of battery voltage is supported.
• LED fault indicators and an LCD screen that can display abnormality information help users to quickly identify system faults. 
• Historical data storage function is available, and data can be stored for up to a year.
• The controller is equipped with an LCD screen with which users can not only check device operating data and statuses but also modify 
controller parameters. 
• The controller supports standard Modbus protocol, fulfilling the communication needs of various occasions.
• The controller employs a built-in over-temperature protection mechanism. When temperature surpasses the set value, the charging 
current will decline in linear proportion to the temperature to curb the temperature rise of the controller, effectively keeping the 
controller from being damaged by overheating.
• Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters to 
extend the battery's service life. 
• TVS lighting protection.

Sunstone Power Co. Ltd. was established in 2003, Sunstone Power has 19 years experience of in manufacturing, marketing, brand name building of lead-acid batteries/battery plates.

Our factories (both plates factory & assembling factory) locate in Kunming City, Yunnan P.R. China. Since Yunnan P.R. is one of the main lead supply areas, we have good advantages of quality control, delivery control, and cost control. So far we are the only factory that gets pollution control permission from the government in Yunnan P.R.

Besides this, we set up our German company in Frankfurt in 2017 and Indonesia company in Jakarta since the end of 2018.

We have our warehouse in both these two countries. It gives fast delivery and stock support to European and Southeast Asian markets.
