  • Min temperature range of -5°C (23°F).
  • Max temperature range of +45°C (+113°F).
  • Weight per kWh: 13 kg (28 lb).
  • Depth of Discharge 90%.
  • Operating humidity 90%
  • Max altitude 2000m

Guarantee.

As guarantee obligations can often be shielded by installer incompetence, should a solar panel manufacturer define an adequately trained installer network with a complimentary warranty extension (added end-user benefit), such guarantee has been considered as a base warranty more likely of adhering manufacturer installation specifications.

Important: A manufacturers obligations under guarantee will be obsolete if the solar battery is not installed to manufacturer specifications. Use an authorised installer.

Affordability.

All well and good having the greatest technology, but what if that technology is simply out of reach for most? Adversely, the cheapest product may lack essential capabilities expected by many end-users. Put price into perspective. Affordability is where price and technology come together to help determine value.
