Overview:

The Mecer Inverter/charger converts DC power to AC power with amazing transfer efficiency.

With it's compact design and aesthetic appeal, the Mecer IVR series is excellent for home use on appliances such as TVs, media centres, lamps or computers

The Mecer IVR series of Inverter/Chargers feature:

• Modified Sine wave output
• Wide input voltage range
• 12VDC or 24VDC available
• Overload and short circuit protection
• LCD display for comprehensive information
• Fully automatic
• Fan to release heat
• Built in 10 / 20 Amp (Selectable) charger
• Optional Solar Charger

DOWNLOAD MANUFACTURER'S SPECIFICATION: MECER IVR MODIFIED SINE WAVE INVERTER

THIS MODEL FEATURES MODIFIED / SIMULATED SINE WAVE OUTPUT!

WE RECCOMEND USING THE DC31 (de-coded - Deep Cycle - Group 31 Case Size Marine Deep Cycle Battery) in Domestic Home Inverter Systems!

The Life Expectancy is 250 Cycles from whatever State Of Charge at Beginning of Discharge to 80 % Depth of Discharge!

MANUFACTURER'S WARRANTY IS:

a) 12 Months / 250 Cycles in Marine Vessel or Leisure Vehicle

b) 6 Months / 250 Cycles in Load Shedding Inverter Application.

BATTERY LIFE EXPECTATION

The DC31 battery has a 1 year manufacturer’s warranty (carry-in owing to normal use) / 200-300 Cycles @ 80 % Depth of Discharge in Leisure / Marine Use.

The DC31 battery has a 6 Month manufacturer’s warranty (carry-in owing to normal use) / 200-300 Cycles @ 80 % Depth of Discharge in Inverter / Standby / UPS Use.

This translates roughly to 200-300 Loadsheddings of 2.5 - 4 Hours Duration (Dependent on load) or 4 - 5 Years Life on Float Charge (Whichever comes first)

Failure to allow sufficient Recharge Time between Loadshedding Events to achieve at least 90 % State of Charge results in ABNORMAL WEAR AND TEAR  due to the battery continuously and repetitively operating in the lower band of State of Charge. An analogy would be operating the Pneumatic Tyres on your car at low pressure (Voltage is "Electrical Pressure")

Fully Discharged Batteries take +- 8 – 16 Hours to fully recharge at the recommended charge rate of 10 % of Capacity. (+-10A Charge on a Wet Cell Calcium Deep Cycle Battery)

We highly recommend that you size your battery accordingly to achieve 4+ hours runtime to Full Discharge (10.5 Volts) Two DC31 Batteries will run 350 Watts of Load for FOUR Hours before reaching the Low State Of Charge Cut Off Voltage.

This results in a Discharge of approximately 50% on a 350 Watt Load after the end of each 2 Hour Loadshedding event, and, at some time during a 24 Hr period, an extended  "rest period" of 10 hours during which the battery can fully Charge to 100 %.

During Eskom Stages 1 - 4 the average loadshedding is 2 hours, this means that the battery will be discharged to +-50% during these Stages 1 - 4, leaving 5 hours charge time (about 50 Ah) to reach "Near Full State of Charge" between Load Shedding events, and, at some time during a 24 Hr period, an extended "rest period" of 10 hours during which the battery can fully Charge to 100 %. 

During Periods of Sustained Stage 5 and higher Load Shedding Events we would suggest reducing loads to bare minimum items needed / turning the inverter output off if not in use / Increasing battery capacity to 4 X batteries and charging current to 20A per battery.
