Xiamen Solar First Energy Technology Co. Ltd

Model Number: ST-MPPT-GG2410A Brand Name: Shenten Key Specifications/Special Features: MPPTadvantage:Maximum power point tracking (MPPT in short) system is a system which allows PV panels to outputs Power by adjusting working condition of the electrical moduleMPPTfunctions:Temperature sensor battery charging compensationOverload protection (automatic restoration)Overcharge protection
Short circuit protection (automatic restoration)
Thunder protection
Reverse discharge protection
Reverse polarity connection protection (automatic restoration)
Under voltage protection

Feature:

• Adopting double crest or multi crest tracing technique, used for the condition when a part of solar panel is under shadow or parts of solar panel is damage.

• Built-in maximum power point tracking algorithm which could promote the energy utilization efficiency of pv system. The charging efficiency is around 30% higher than PWM mode.

• It can find out the best working point of I-V curve within 1 minute. the MPPT efficiency could reach to 99.9%.

• Adopting advanced digital power supply techniques which makes the energy conversion efficiency reach up to 97%.
• Four charging stages: MPPT - equalizing charge- boosting charge- floating charge.
• With current-limiting charging mode. When the power of solar panel is oversized， the controller will lower charging power automatically, which enable the system to work under the rated charging current.
• Have the fault code indication, it helps user confirm the system fault.
• Various load control methods. Could recognize day and night automatically.
• Various system protection functions. Including over-charge, over-discharge, over-load, over-heat, battery-reverse connection and short-circuit protection etc.
