Battery of

Small capacity

In a battery pack, the one with small capacity will easily get over charge

and over discharge, so the service life of whole pack shall be influenced

Active balance technology

With such technology, the energy could be

transferred and balanced between each battery

in the pack at any time without any energy loss


Unify battery performance by active balance technology at ay time

Features & Benefits Narada active container

More PV energy extraction

Our unique architecture extracts more energy

from the solar panels with the mlt charging

regime, by actively extending the PCS’s MPPT,

while it has already achieved full output

When DC:AC ratio is more than 1.1, the internal

DSP controls will dynamically optimize the ESS

voltage to maintain the inverter at maximum

output while also charging the batteries with

the excess energy from the Solar PV panels,

creating greater cash flow for our customers
