Flatpack2 Solar Charger 24V, 1500W HE – (Solar)
Part number 241115.660. This galvanic isolated solar charger
may be integrated in green telecom applications to supply
24VDC loads, otherwise is similar to "Flatpack2 Solar Charger
48V, 1500W HE – (Solar)", page 17.
For technical data, read chapter "Specifications Flatpack2
Solar Charger 24V, 1500W HE – (Solar)", page 37.
Flatpack2 Solar Charger 48V, 1500W HE – (Solar)
Part number 241115.650. With the Maximum Peak Power
Tracking (MPPT) algorithm ensuring close to 100% panel
utilization and efficiency up to 96.5%, the galvanic isolated
solar charger sets new standards for renewable power in
totally green telecom sites.
The charger uses a digitalized advanced control algorithm
that finds the solar panel voltage that generates the
maximum power
charging is continuous according to performance profile for
panels. In addition to finding the profiles peak power a full
scan is performed at a fixed interval to stay on peak even
with panel failures and major shadings. This gives close to
100% panel utilization.
The Flatpack2 HE SOLAR charger is suitable for any telecom
site with autonomous (solar only) or hybrid solar power.
It can be used in parallel with any other Flatpack2 rectifiers
(front-to-back air flow systems only) fed by generator or
unreliable mains, on hybrid sites.
Solar chargers must be mounted in dedicated solar power
shelves with correct DC input feeding, see Figure 2, page 7.
Refer to chapter "Specifications Flatpack2 Solar Charger 48V,
1500W HE – (Solar)" on page 38.
