In their own words

• Any changes without prior notice! • Final interpretation right of the manual belongs to our company. • Confirm that power connections are tightened to avoid excessive heating from loose connection. • Do not allow water to enter the controller. • Install external fuses/breakers as required. • There are no user serviceable parts inside the controller. Do not disassemble or attempt to repair it. • Product design has not considered any losses occurring due to cable and connectors use necessary cable and proper connectors to prevent additional losses. General Safety Information 6. Irreclaimable mechanical damage. 5. Damage results from acts of nature such as lightning, weather extremes 4. Damage occurring during shipment. 3. Unauthorized product modification or attempted repair 2. PV current or PV voltage exceeding the ratings of product. 1. Damage by accident, negligence, abuse or improper use. • This warranty does not apply under the following conditions: a problem with the controller. Return the defective product to us with shipping charges prepaid if problem cannot be solved. Provide proof of date and place of purchase. To obtain rapid service under this warranty, the returned products must include the detailed nature of the failure, the solar module type and size, type of batteries and system loads. This information is critical to a rapid disposition of your warranty claim. Before requesting warranty service, check the Operation Manual to be certain that there is • Claim procedure: (5) years from the date of shipment to the original end user. We will, at its option, repair or replace any such defective products. The MPPT Solar charge controller is warranted to be free from defects for a period of FIVE • Warranty Period Red Fast Flashing Over-load Shutdown Red On Solid Battery is over discharged Red Off Battery status normal Green Fast Flashing Battery charged/Float charging Green On Solid Battery charging Green Off Battery charging OFF Colour Indicator Status Charging Status LED indicator After the battery is fully charged in the Boost/absorption voltage stage, the controller reduces the battery voltage to the Float voltage set point. The purpose of Float stage is to offset the power consumption caused by self consumption and small loads in the whole system, while maintaining full battery storage capacity. In Float stage, loads can continue to draw power from the battery. In the event that the system load(s) exceed the solar charge current, the controller will no longer be able to maintain the battery at the Float set-point. Should the battery voltage drop below the Boost set-point, the controller will exit Float stage and return to Bulk charge. Float Charge When the battery has been recharged to the Boost/absorption voltage set-point, constant-voltage regulation is used to prevent heating and excessive battery gassing. The Boost/absorption time is 120 minutes. Boost/absorption Charge In this stage, the battery voltage has not yet reached boost voltage and 100% of available solar power is used to charge the battery.
