What are some key parameters of energy storage systems?

Rated power is the total possible instantaneous discharge capacity of the system, usually in kilowatts (kW) or megawatts (MW). Energy is the maximum energy stored (power rate in a given time), usually described in kilowatt-hours (kWh) or megawatt-hours (MWH).

What are the application values of industrial and commercial energy storage systems?

Peak-valley arbitrage To reduce corporate electricity costs, utilize the difference in peak-valley electricity prices, charge in valley periods and flat periods, and discharge in peak and peak periods.

What information about the power-consuming enterprise is necessary when installing an energy storage power station?

Basic information: electricity type, basic electricity price, time-sharing period/time-sharing electricity price, and the company's electricity shutdown production situation;

Stacked-PV MPPT Solar Controller

The Stacked-PV MPPT Solar Controller is specially developed for PV capacity expansion at base station sites. Using a series-connection scheme, the system consists of PV modules, a stacked-PV MPPT controller, and a DC meter. Each PV string is series-connected to the controller, which steps down the module output voltage to −48V and injects it onto the rectifier output busbar to supply DC loads. Designed for communication base stations, it supports wall-mount and pole-mount installation. The product is available in outdoor and rack-mount versions.

Product Features

Supports wall-mount and pole-mount installation, suitable for both indoor and outdoor environments
High efficiency: combines multiple MPPT algorithms for a conversion efficiency of up to 97%
High quality: uses internationally leading-brand components for superior electrical performance, high reliability, and long service life
High safety: Protection Rating IP55, supports outdoor installation, built-in circuit breaker and lightning/surge protection
