Technical Specifications

What does the Pro Combi range offer?

On the battery charger side

  • 4 step constant current battery charging
  • 8 pre set battery type selector plus de-sulphation
  • powerful charge rate
  • will charge totally flat batteries
  • PFC, draws about 30% less power than conventional units

On the crossover side

  • 20 m/s crossover time, will not to lose any equipment due to power loss
  • 30 amp through current ability on all models
  • twin 30 amp / single 50 amp on the 3500 watt models

On the inverter side

  • high overload ability
  • high temperature rating
  • low quiescent current
  • power saver mode to automatically reduce power
  • allows through power even with no batteries connecte

On the remote control

  • ability to switch the unit on/off
  • ability to select or de select power saver mode

General

  • removable local panel to give remote control with waming and function I.e.d.
  • remote on/off plus remote power saver on/off
  • 10 metres remote cable
  • almost 20 alarms/ warnings/and information

General Features for ProCombi Q

General Features for ProCombi S

  • Remote control: front control panel removable as remote
  • Size (mm) (w x h x l): 185 x 180 x  430 (1600 & 2500); 227 x 180 x 512 (3500)
  • Weight: 20kg (1500); 20kg (2500); 24kg (3500)

There are 2 main models the Pro Combi Q for quasi-sinewave) and the Pro Combi S (for Pure-sinewave). So the simple question is what best suits your needs?

Pro Combi Q, (quasi-sine model) suitable for most installations, where you would use a microwave, fridge, hair dryer, vacuum cleaner, kettle, computer, etc The vast majority of products will run on quasi-sinewave.

Pro Combi S ( sine wave model ) where all the above plus washing machines, bread makers , thyristor controlled equipment are used - then sinewave is required
To make the choice even simpler, we have a 6 months exchange/upgrade policy.

If you purchase a Pro Combi Q and find there is some equipment that you cannot run due to the Quasi Sinewave and require Pure Sinewave, Sterling are happy to up-grade your quasi-sine unit for sinewave with the only cost being the difference between the 2 products (unit must be sent direct to Sterling and in good condition).
