Chinese energy storage company Dyness has released a new energy storage system for balcony solar systems.
Each Junior Box unit weighs 18 kg, measuring 42 cm x 28.35 cm x 24.5 cm. They feature removable battery management systems (BMS) and maximum power point tracking (MPPT) modules for simplified maintenance.
Each battery unit has a maximum input power of 1,200 W and a maximum output of 800 W. A smartphone app can be paired with the system to control the output of the battery and its usage modes.
“When operating in load-first mode, the user can set the power to the microinverter through the Junior Box, and when available solar energy is insufficient, the Junior Box and PV panels supply the energy to the home circuits,” the company said. “In battery priority mode, you can set the power to charge the battery, prioritizing the battery and powering the home with excess energy.”
