Magnum Energy MagnaSine MS4448PAE Inverter/Charger Review

Remote off-grid power or residential utility grid-tie battery backup: Not only is the MS4448PAE famous for off-grid residential AC solar power needs, it is a robust and reliable backup for uninterrupted power for your on-grid home.

No series stacking for 240VAC required: The unique design of the MS-PAE Series can provide 120 and 240 volts output in one unit, eliminating the need to stack two units together to obtain 240 volt output.

Parallel stack MS4448PAE inverters for more power: You can parallel up to four inverter / chargers for up to 17.6kw of power at 120/240V. The MP panels and router are required for parallel stacking the MS-PAE Series. Contact us for details.

Power Factor Corrected (PFC) Charger: Magnum's PFC battery charger technology is built into the MS4448PAE inverter-charger. It uses less energy from a generator than a standard charger – using 25-30% less AC current than standard chargers.

The Magnum MS4448PAE is safe and reliable: ETL Listed to the stringent requirements of UL 1741, 1st edition, and CSA C22.2 #107.1-01 for renewable energy installations.
