MidNite Solar E-Panels Explained revised 3-08

When the pre-wired MidNite E-Panels first came out late in 2005, the choices were easy. You were limited to an

OutBack inverter and all you had to do was to pick the correct breaker size. Well we’ve managed to accommodate many

dealer and installer requests, but along with these enhancements come additional choices. To help lead you in the right

direction, we’ll cover different inverters and explore the many options available within each platform.

This is the basic E-Panel made for all of the OutBack FX

&VFX inverters. The enclosure is only 9.5 inches wide and

25 inches tall.

The main features are it’s small size and low cost.

The main drawback is also the small size. The picture here

doesn’t show it, but the insides have undergone a radical

change in the form of individual AC busbars rather than the

single AC block. This change allows up to 14 connections per

circuit rather than only 5. This enclosure is available as a

right hand hinged unit or left (door swing and breakers for a

left version are opposite from the right hand version shown)

Another configuration to this series is the availability of an aluminum enclosure vs. the standard steel unit. Steel units

are powder coated gray and the aluminum is white. The white aluminum E-Panels are used in places like Hawaii or

Maine or wherever salt air is a factor. Aluminum E-Panels also weigh 9 pounds less than the gray steel versions. Some

customers just like the look of white, and order aluminum just for that reason.

These E-Panels comes standard with the AC bypass and AC input disconnect pre-wired, din rails for 6

additional 13mm wide AC or DC breakers, battery breaker installed with inverter plus and minus cables, 500

amp/50mV shunt, battery plus busbar, battery minus busbar, AC busbars, ground busbar, DC cover, AC flex conduit

tubing with couplers, MX60/Classic mounting bracket, grommets and bushings, numerous knock outs for cable entry

and exit, lots of hardware for mounting inverter, charge controller etc, wall mounting brackets, installation instructions,

wiring diagram mounted on the door, and a tech support phone number. Check out the before and after pictures below.

This person couldn’t afford the regular OutBack breaker boxes, so just did without until MidNite came along. These

pictures are what it is all about!

Model numbers and descriptions for regular FX & VFX OutBack E-Panels:

MNE125ST-L 125 amp breaker in the gray steel chassis, left hand hinge & breakers

MNE175ST-L 175 amp breaker in the gray steel chassis, left hand hinge & breakers

MNE250ST-L 250 amp breaker in the gray steel chassis, left hand hinge & breakers

MNE125AL-L 125 amp breaker in white alum chassis, left hand hinge & breakers

MNE175AL-L 175 amp breaker in the white aluminum chassis, left hand hinge and breakers

MNE250AL-L 250 amp breaker in the white aluminum chassis, left hand hinge and breakers

Change the –L to -R” at the end of the model number to signify right hand hinge. (example: MNE175AL-R). Note that

all E-Panels can be swapped from a left hand unit to a right hand unit in the field. This requires a $59.00 steel or a

$65.00 aluminum left hand door and a couple hours of work. It is easier to have it built as a right hand unit at the factory

where there is no additional charge for a right hand door. Note: As of Nov 20, 2007, Left hand hinges are the standard.

To receive a right hand hinge, specify as such. Many new MPPT charge controllers need Left hinges for mounting.

Prices: Basic gray steel 175/250 amp retails for $479, white aluminum 175/250 amp runs $519, Basic gray steel

125amp $439, white alum125 amp $479

Stretched OutBack E-Panel for GFX, GVFX, FX, VFX Some installers that use a lot of E-Panels have asked for additional room inside the E-Panel. We created the Stretched OB version for these professionals. It is based on the 50% wider Magnum Energy chassis. In addition to more room to work, you also get a PV input busbar, Battery Plus and DC negative busbar. No need for ring terminals anymore with this system! There are also additional knockouts top and bottom for lightning arrestors and cabling.

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 Magnum Energy 240VAC E-Panel for MS and RD series This is our flagship E-Panel. It encompasses every suggestion and update we are aware of. It also accommodates the new Magnum Energy MS4448-AE and MS4024-AE inverters. These inverters are a true 120/240 input and output. Unlike the regular Magnum MS and RD series that have a second 120VAC pass through leg, these inverters are like having a stacked pair of inverters. It will charge from either a 120VAC source or a 240VAC source.
