Product Description

3KW/5KW/8KW/10KW/20KW/30KW/50KW off grid battery system                                                               

Off grid battery system including solar panel array, solar charge controller, storage battery, Off grid inverter, etc. In the sunshine, the solar panel convert the solar energy to DC power and charge the battery group by the charge controller. Then the off grid inverter convert the DC power into AC power for power supply the AC load.

Off grid battery system Introduction: 

1. Solar Panels

  • Industry leading power output warranty, 25 year 80%, 10 year 90% power warranty and 5-year power warranty of materials and workmanship
  • CE, TUV, ETL, ISO9001:2008 (Quality Management system) certified factory Product Quality warranty & products Liability Insurance to guarantee and user' benefits.

2. PV Combiner Box with lighting protection 

  • Applicable for outdoor PV systems;
  • Each PV array attached to DC fuse protection and anti-reverse protection optional;
  • Wide DC voltage input range with maximum open-circuit voltage up to 1000V;
  • High voltage lightning protection (SPD) special for PV;
  • PG Cable glands input, convenient and safe system wiring;
  • PV special high voltage circuit breaker control output;
  • Protection class IP65 for outdoor use;
  • Output Waterproof terminals

3. Solar Charge Controller

  • Excellent EMC design
  • Industrial-grade chip
  • Full enclosed duct design and high speed fan for cooling
  • Users can parallel connect lots of our controllers in a system
  • PWM Charging technology: fast charging, equalize charging and float charging
  • Advanced battery activation technology increases battery lifetime 30% at least and improves the system performance
  • Temperature compesention function compensates the voltage based on different temperature
  • Infineon IGBT module or IR MOSFET ensures stable performance
  • New SOC method indicates the power generation information of daily, monthly and total
  • 3''LCD+LED display+touching keys as HMI makes the operation more easy
  • RTC function indicates the real time and temperature
  • The second protection will protect battery from destroying when the power switch (IGBT) is down (optional function)
  • DC output function (Optional function)
  • Standard modbus protocol for RS485 or GPRS communication. 
4. Off Grid Inverter 
  • SANDI off grid inverter inside with low frequency isolated transformer, 100% full power output, can work 24*7
  • High efficiency >94%
  • Design service life > 20 years
  • All components we used is best quality, such as Japanese Mitsubishi IPM intelligent module, brand circuit breaker, big LCD display.
  • Inverter's powerful function is more advanced than others, such as:
  • Variable frequency start which has stronger capacity to drive load
  • The DC input voltage range, output voltage, output frequency 50Hz/60Hz all can be set
  • AC bypass input and RS485 monitoring (Optional)
