About Photovoltaic Energy StorageThe Equalizer is a small device that actively equalizes the voltage between battery packs. When it detects a voltage difference between different battery Cells, it kicks in and actively transfers energy …
About Photovoltaic Energy StorageThe Equalizer is a small device that actively equalizes the voltage between battery packs. When it detects a voltage difference between different battery Cells, it kicks in and actively transfers energy from the battery with the higher voltage to the battery with the slightly lower voltage. This creates a voltage balance throughout the …
About Photovoltaic Energy StorageBatteries are specified by three main characteristics: chemistry, voltage, and specific energy (capacity). Chemistry refers to the type of materials used, voltage indicates the electrical potential difference, and specific energy represents the battery''s energy storage capacity.
