First, let's get design specifics out of the way. Here’s a list of a few technical specs:
- Pure Sine Wave
- 4,000 Watt, 48 Volt Inverter/Charger
- Provides both 120 and 240 Volt output in one unit
- Enables paralleling of multiple inverter/chargers

There are two types of inverters, Modified Sine Wave and Pure Sine Wave. The 2 diagrams below show the difference between the two. A modified, or square, sine wave rises in steps, whereas a pure sign sign wave rises and falls smoothly. This means a pure sign wave inverter will run more smoothly, with less hiccups than a modified sine wave inverter.
A fair amount of quality inverter/chargers in this class provide just 120 volts, making it necessary to purchase and install two to get the 240 Volts needed for items such as water pumps and water heaters. The MS4448PAE is one of the few inverter/chargers of this capacity that provides both 120 and 240 Volts. This helps with the overall price of the system, and easier installation and wiring. When designing our own system for our homestead, we needed a reliable 240 Volt inverter capable of running our deep well submersible pump. For example, we are able to supply water to our homestead from a well depth of over 100 meters. With a MS4448PAE we only needed to purchase one unit.
If you find out you’re not producing the power you need, no worries. The MS4448PAE is versatile. You can expand your system by paralleling up to 4 inverters for up to 17.6 kW of power at 120/240 volts. In addition to the inverter, you will also need to purchase an MP Panel, router and extension kit to complete installation of an additional inverter.
We’ll take reliability over bells and whistles any day.
One of Magnum’s top distributors, Invertech (http://www.invertechhaiti.com/), is located in Port au Prince, Haiti. We installed a PV system on an NGO mission building in Port au Prince and we got to meet the good folks at Invertech. We were impressed with their operation that included being an authorized service center for Magnum. We found that Magnum is king in Haiti, with a huge concentration of all types of Magnum inverters. Most people we had a chance to talk with said Magnum inverters in general are strong, rock solid pieces of equipment. We couldn’t agree more.
