Such hybrid solar system can work as both solar on grid system and solar off grid system. It can utilize electricity price difference, charge battery at low price and discharge at high price to maximize system profit, compensate local transformer limit. It can  provide back-up power supply for unstable grid, during grid failure, seamless switches to off-grid mode within 20ms to realize uninterruptable supply

The 30kW off grid solar power system can be used for remote area without grid connection. Wifi or GPRS monitor can be avaible for such system.  Inverter power: 6pcs 5kw in parallel AC output voltage: AC220V/230V/240V or AC380V/400V/415V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatiable with generator Monitor: WIFI or GPRS

The on grid solar power system converts the solar energy into electrical energy, without the storage battery, and directly sends the electrical energy to the grid through the grid-connected inverter. Inverter power: 10kW AC output voltage: three phase Solar panel type: mono or poly

1. Supports lead acid battery and li-ion battery connections. 2. With a dual activation function when the li-ion battery is dormant; either mains/photovoltaic power supply access can trigger the activation of the li-ion battery. 3. Support split-phase and single-phase pure sine wave output. 4. Supports four different voltage levels of 100Vac, 105Vac, 110Vac, and 120Vac per phase. 5.

Flexible solar panels differ quite from rigid, rectangular, glass-encased standard solar panels typically found on rooftops. Rather, flexible solar panels come in all shapes and sizes and are expected to be used in a greater number of situations than standard panels Whereas portable solar panels contain solar cells mounted in a lightweight, often plastic frame and thin-film panels are made of materials like copper, selenium, and gallium, flexible and standard solar panels use solar wafers to convert sunlight to electricity. Most often, flexible panels use wafers made from silicon, though they are far thinner than those in standard panels-as thin as merely a few micrometers in width. Whereas standard panels are sandwiched between layers of glass, flexible panels are placed between layers of protective plastic.
