LCD Display 3kw 5kw 24V 48v Solar Inverter Off Grid Mppt Solar Power Inverter Hybrid Solar Inverter
SP500 off-grid suitable for single-phase inverter without electricity, nomadic, communications base stations, the power instability regions, islands, border posts, area management office, kiosks supporting PACK battery cell manufacturers. With LED display, support USB / RS232 / RS485 / Bluetooth, compact and highly cost-effective.
Wave-by-wave current limit
- When the output current exceeds the wave-by-wave current limit point, the hardware current limit protection is triggered, which can restrain the rise of current to a certain extent, so that the current does not exceed the inverter protection value, and avoids shutdown due to sudden load or abnormal current causing current alarm.
Design high protection
- Duct isolation, after heat treatment heating devices heat introduced into the duct, sensitive electronic device is placed in a confined environment, prevention of environmental pollution.
Intelligent and easy to use
- A key security settings, easy to set all the parameters and network
- Built-in independent RTC clock chip to support 25 years of power generation data storage
- PC, mobile phone local/remote intelligent maintenance
- In response to the power grid scheduling, support smart microgrid energy management
- Integrated reactive power regulator
Safe and dependable
- Aluminum chassis overall design, thermally enhanced corrosion resistance and rust resistance, extend the life of
- Built convection fan, to reduce the temperature of the core member, extend the life of
50C ambient temperature without derating:
- Independent duct design, rapid cooling, high temperature and low temperature machine
- Environment without derating use. Rapid cooling, without derating
Overcurrent protection suppression
- By real-time monitoring of the load current, defined automatically run when it is not suppressing the overcurrent exceeds a set point, to prevent excessive current tripping fault caused, for some inertia or big change of load, which is particularly useful.
Overvoltage suppression protection
- When the bus voltage reaches or exceeds the bus overvoltage suppression point during the operation of the inverter, the inverter will automatically adjust the operating frequency to suppress the rise of the bus voltage, so as to ensure that the inverter does not cause overvoltage protection due to excessive bus voltage.
