5KW off-grid inverter for solar power generation system
Description:
Gtech VMH Series solar inverter with the characteristics of high efficiency, steady performance and easy system expansion.
The SMART VMH series is an integrated control machine of pure sine wave high-frequency solar inverter. The controller adopts advanced MPPT calculation method and intelligent battery management to ensure the maximum energy acquisition. With a wide PV input range, the inverter can be carried without battery when the energy is sufficient. It has the advantages of high-power density, simple operation, high overall effi ciency, and small no-load loss. The inverter integrates the 3-in-1 function of solar energy, mains power and battery, which can be used for lighting, computers, televisions and other household appliances and electric tools, as well as small-scale industrial electrical equipment.
Features:
• Pure sine wave output
• Built in MPPT solar controller
• Configurable AC/Solar input priority and output priority via LCD settings
• Wide and selectable AC input voltage range
• Multiple protections of battery over discharge, overload, over temperature, short circuit
• Automatically turn on after the mains is restored
• Cold start function; USB and RS232 monitoring functions
• WIFI/Bluetooth intelligent monitoring , support mobile APP function(optional)
• Selectable charging for different types of battery via LCD setting
