the PowerBack PB5000 is able to supply the majority of mains operated domestic and office
appliances, including small motors, lights, fans, refrigerators and air conditioners up to a maximum
total demand of 5kVa.
Note: In extreme circumstances where the utility supply remains off and the battery back up has
expired, appliances such as fridges and air conditioners require approximately 3 minutes restart
delay (time is required to balance the refrigerant gas) before utility mains is reinstated . Please
contact Sollatek distributors for advice on the Sollatek Voltshield premium range of products.
Positioning of PowerBack and battery system
the Powerback is designed to operate in a restricted access location, lockable and accessible only
by competent persons. Installation must be in accordance with the requirements of IeC 60364-4-42.
the PowerBack must be installed in a dry shaded and dust free location with 300mm spacing all
round the unit to allow adequate ventilation. the unit has forced cooling and the fans operate full time
(Saver mode allow fans to turn off when no load applied)
Batteries must be installed in a dry shaded location. take extra care to ensure there is adequate
ventilation to prevent build up of explosive gases (depending on battery type used).
Batteries
the PowerBack requires a 48V dc battery bank with an absolute minimum capacity of 100ah, 200ah
is the recommended minimum capacity to provide a realistic backup time (autonomy). Please refer
to figure 2 for battery set up. Before proceeding, ensure you have appropriate sized batteries for this
inverter. the unit can use deep cycle flooded lead-acid, or sealed Gel/aGM lead-acid batteries so
ensure that your batteries are in one of these categories.
