Industrial power inverters are practically a necessity in nearly every organization. They help maintain minimal downtime during power outages and ensure a continual power source so that your machinery works all the time.
Inverters need about 8-10% more power than appliance power load
While modular inverters are built to serve, there are some things you need to know about them. For example, thanks to the inverters’ efficiency, they generally need about 8-10% more power than the power load of appliances being run.
The best way to find out how many DC amps you’ll be using from your battery is by dividing the appliance’s AC wattage by 12 or 24 if it’s a 24v system. Then multiply the result by 1.1 to get an estimate of the DC draw.
Inverters draw power from batteries even when the unit is turned off
It’s important that you know that inverters tend to draw power from your batteries if the unit is turned on but is not in use. Based on the unit and design of the standby system, the inverter can draw as much as 0.02 to 2 amps of power.
So just imagine. If you leave the inverter switched on without any load or appliance connected to it, the batteries stand to draw an average of about 1 amp of power per hour. This spells about 24 amps of power a day and 168 amps a week, which is a complete waste of power and money.
The simplest and best solution in preventing this unnecessary loss of power and money is to turn off the inverter when not in use. In fact, if you look, there are many inverter manufacturers, like exeltech.com, that have this feature included in their inverters as a standard feature. Some may not have it as a standard feature but at least have an optional remote on/off control.
