E-Panels Explained

The Magnum Energy 120VAC E-Panel for MS and RD series
Magnum Energy makes a very interesting line of inverters, both modified and pure sine wave. The RE industry is
embracing both types of inverters so MidNite builds E-Panels to accommodate all of the RD and MS series. The insides
of the Magnum 120VAC E-Panels look much like the Stretched OutBack. Internal AC wires are routed to match the
Magnum inverter rather than OutBack. The accessory components like the DC cover, top shield, remote bracket and
such are specific to the Magnum E-Panels. Like the Stretched OB E-Panel, the Magnum has a PV input plus and DC
plus busbar as well as the regular AC input and output busbars. This chassis is 14.4 inches wide, so has ample room for
all your wiring needs. The chassis is only 3.5” deep so wiring access is the best in the industry. All of the present 12 and
24 volt Magnum inverters have a 120VAC inverter/charger input/output as well as a 120VAC input/output that does not
go through the electronics. It is strictly a pass through for the other leg of a 240VAC input. The pass through leg can be
useful when attempting to utilize both legs of a 240VAC generator. One leg is used for charging and the other is used to
pass through to your 240VAC deep well pump. The 120VAC E-Panel here is not able to handle the extra leg of AC, so
look to the 240 E-Panel to accommodate this unique feature. Normal installations jumper AC 1&2 on the inverter for 50
amp service at 120VAC.

The picture above right tells it all. Installers get the chance to assemble the power electronics, inverter, charge
controller, breakers, arrestors, battery status monitors, displays etc in the shop. The system as shown here can be tested
in the shop to insure that the system is functioning properly. This is one major advantage in using the E-Panel system.
These E-Panels can be field modified to be right hand units. A right hand door is required to do this in the field.
Magnum all wired up and tested with lightning
arrestors, charge control disconnects, charge
controller and remote display ready for transport to
the job site. A DC-GFP and battery status monitor
could also have been added to this assembly.
