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

Every module (module 1 to 5) within the rack will report its own status, warnings and alarms. Most of them are
repeated here as the M1000 will handle and store those status summaries, warning and alarms on top of
controlling the performance of each module. Beyond its control, monitoring and storage (max. 30 days)
function, it also communicates all the parameters from cell, module and rack info to the ExiNMS manager.
