 | How do I choose the right Juice box? Make a list of the components you will be running and take note of their individual power requirements, input type and running hours. For example Fred would like to run a small office in Kenya. He will be running a laptop for 8 hours p/d, powering 2 LED fluorescent tubes 4 hours & running a printer for a few minutes. Laptop 60 watts running 8 hour p/d 60x8 = 480w p/day. Lighting 2 x 12 w running 4 hours p/d 12 x 2 x 4 = 96w p/day Printer 150 w x 10min p/d = 150\60 x 10 = 25w p/day Total consumption 601 W / day or divide by 12 to equal 50 Amps We then have to account for a day of bad weather as well as natural power losses. Rule of thumb is to subtract 30% Fred now requires 900 W or 75 Amps p/day to run his office. He would require an MX 102 Pure with a 180 W solar panel.
Laptop 60 w or 5 Amp/per hour 12 V or 220v Pure Sine Led lighting 12 w or 1 amp 12V Printer Fax machine Radio Lcd tv Devices that DO NOT RUN on modified sine wave invertors
