About the Sollatek PowerBack Inverter

The Sollatek PowerBack S range – is an inverter/charger unit that will accept Mains as well as Solar charging. This Linear/Transformer-less range is suitable for high-performance applications and is especially useful in remote areas where mains charging is scarce and solar availability is abundant. The PowerBack can provide mains-like power for all your essential appliances and lights. The PowerBack charges the batteries when mains power is available.

The backup time the PowerBack can provide in a power cut depends on its overall capacity (determined by the number of the batteries connected and their state of charge), as well as the type and number of appliances connected to it.

Main Features and Benefits:

  • Solar charging input up to 3750Wp (depending on model)
  • Selectable charging current up to 25Amps (depending on model)
  • Suitable for all type of appliances and electrical and electronic equipment
  • Compact size (excluding batteries and installation accessories)
  • Highly efficient back up when critically needed
  • Built-in MPPT solar charge controller for optimum harvest sun power
  • Fast transfer time (20 milliseconds) comparable to offline/line interactive UPS
  • Transfer time configurable to cope with Genset output power
  • Three-step intelligent charging to reduce recharge time
  • Intelligent fan cooling determined by the load
  • Supports heavy-duty appliances like air conditioners
  • Multiple operation modes to meet every configuration with Solar and mains
  • Low battery alarm
  • Compact in size (excluding batteries and installation accessories)
  • Rack design & wall-mounted design for flexible installation
