EltekWith the MPPT* algorithm ensuring close to 100% panel utilization and an efficiency up to 96.5%, the galvanic isolated solar charger sets new standards for renewable power in telecom.
The combination of innovative design, efficiency and reliability makes the Flatpack2 HE SOLAR stand out.
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 feed by generator or unreliable mains on a hybrid side.
The Flatpack2 HE SOLAR charger is fully integrated with the standard Flatpack2 family which means it can be used in any 48V FP2 system solutions with“4AC”power shelves and Smartpack controller. Typically each charger is fed by one string of 4 to 6 solar panels. Galvanic isolation between solar panels and batteries/ telecom equipment provides high level of surge protection and reliability.
The Flatpack2 HE Solar module is CE marked and UL listed for world wide installations.
The charger uses a digitalized advan ced control algorithm that finds the solar panel voltage that generates the maximum power independent of sun availability. The 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.
All standard control and monitoring features are available with solar charger plus additional feat ures like warnings for shaded/ dirty solar panels and energy monitoring.
Integrated energy logging feature will monitor the power supplied from solar panels through the charger.
Energy log is stored on a historical basis in controller. The kWh or Wh supplied and consumed on site is stored on hourly, daily and weekly basis. Values can be seen 52 times back in time from the last log.
To minimize fuel consumption on a hybrid site the controller utilizes calculated backup capacity data and optional time delay to give start/ stop signals. Fuel tank level monitoring gives full visibility of consumption, theft and refill interval.
Forced charging can be triggered by daily time schedule, monthly periodical run time and emergency charge based on fast battery voltage drops. Charge mode during generator run is selectable between normal temperature compensated float charge and boost charge.
