3KW Integrated outdoor solar power system 2.56KWH
■ The whole system integration includes an off-grid solar inverter module, lithium iron phosphate
battery pack, PDU, and outdoor cabinet.
■ The system is commonly used in the corner of the city, remote roads, mountains, bad environments,
dust, moisture, rain, mist-erosion, very poor power qual ity in the area.
■ The system provides a continuous pure sine wave AC power supply for outside communications/network
■ It adopts full-digital double closed-loop control, combined with advanced SPWM technology to output
pure sine waves.
■ Two output modes: mains electricity bypass and inverter output; uninterrupted power supply.
■ Four charging modes: PV Only, Mains Electricity Priority, PV Priority, and PV&Mains Electricity hybrid
■ Advanced MPPT technology with 99.9% efﬁciency.
■ Comes with an LCD display and 3 LED indicators that can clearly indicate the status and data.
■ Power saving mode, reduce no-load loss.
■ Intelligent variable-speed fan to efﬁciently dissipate heat and extend system lifespan.
■ It comes with double l ithium battery activation modes: mains and PV, and supports lithium battery
■ All-round protection for solar panels includes overload and short circuit protection, under-voltage and
over-voltage protection, and reverse polarity protection.
■ With sun protection, heat insulation, roof venti lation.
■ With waterproof and the ﬁltration dust inlet.
■ The cabinet body is designed for the IP55 protection level. The cabinet front door shutters with
waterproof design, on the back of welding outdoor cabinet.
■ Modular design is easy to maintain.
■ System conﬁguration AC and DC lightning protection.

■ Wide input voltage, avoids frequent switching to battery power because of large power grid voltage,
reduce battery failure probabi l ity, adapt to the power environment in poor areas.
■ The environment which require higher IP level, we use heat exchanger to effectively reduce the
temperature of box inside and improve IP protection level .
■ Long-term storage of the battery needs to be placed in a dry, clean, dark, and well-ventilated indoor
environment. The suitable storage temperature range is -20~35℃.
■ Batteries must be stored and transported in a state close to 50% SOC.
■ For long-term storage, the electricity needs to be cycled every 6 months.
■ When loading and unloading the battery during transportation, please be careful not to drop it,
do not stack it over 4 layers, or place it upside down, and ensure that the front is facing up.
