Home energy storage devices store electricity locally, for later consumption. Electrochemical energy storage products, also known as "Battery Energy Storage System" (or "BESS" for short), at their heart are rechargeable batteries, typically based on lithium-ion or lead-acid controlled by computer with intelligent software to handle charging and discharging cycles.

These systems provide homeowners with the ability to store excess energy during times of low demand or high renewable energy generation and use it later when there is a higher demand or low renewable energy availability.

At present, the energy storage equipment required mainly includes BMS battery management system, photovoltaic grid-connected inverter and energy storage inverter. In view of the above requirements of home energy storage equipment, and combined with the safety isolation characteristics of each unit circuit of photovoltaic system, Crossvalley Solar proposes a complete set of power supply solutions for control units.

In recent years, photovoltaic power generation technology has advanced rapidly, and the installed capacity has increased rapidly. However, photovoltaic power generation has shortcomings such as intermittent and uncontrollable. Before processing, large-scale direct access to the power grid will bring great impact and affect the stable operation of the power grid. Adding the energy storage can make the photovoltaic power generation smoothly and stably output to the power grid, and the large-scale access to the power grid will not affect the stability of the power grid. And photovoltaic + energy storage, the system has a wider range of applications.

The 20kW off grid solar system is suitable for area without grid or grid is unstable. It can be compatible with generator to saving electricity bill and increase the power quality. Inverter power: 4pcs 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 Compatible with grid and generator Monitor: WIFI or GPRS

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 40kw off grid solar sysem is normally used for area without grid connection or grid is unstable such as farm, hotel, small factory. Inverter power: 40kW power frequency inverter Inverter type: power frequency AC output voltage: AC380V Battery voltage: DC240V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatiable with generator

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

On-grid means your solar system is tied to your local utility's GRID. Being grid-tied is beneficial because you don't have to buy an expensive battery back-up system to store any excess energy.
