What type of system do I
need?
www.midnitesolar.comPh. 360-403-7207 Fax 360-691-6862
• Off Grid. • Battery Based Grid Tie.• AC Coupled.
All of MidNite Solar’s Pre Wired systems are fully customizable for
your needs
Off Grid
• Stand alone system• Will not sell back to the
utility• Various inverters available
for Off Grid (Some will do both)
• 120 or 120/240?

Grid Tie With Battery Backup• Sells to the grid• Runs critical loads
during grid failure• Do you need 120vac
or 120/240vac• Some models support
generator input as well

AC Coupled
• Adds battery backup to a purely grid tie system.
• Adds some complexity to the system.
• Best suited for existing grid tie systems as an add on.

• Growing market segment• Can be confusing!• Can be complicated!• Numerous ways to go• MidNite has taken most of
the mystique out of the equation

AC Coupled
What is AC Coupled ?
AC Coupling is a controlled back feed to a battery based inverter A back feed is hooking up AC to the output of an inverter AC coupling is a synchronized back feed. The grid tie inverter shifts frequency to match the battery based inverter before connecting. This makes it ok to do.

What is AC Coupled ?
Not all battery based sinewave inverters are capable of back feed.
Your choices in North America are:
SMA Sunny IslandOutback FX, VFX and
RadianMagnum PAE seriesSchneider XW series

• Magnum and OutBack inverters sense circuits that control charging are on the AC inputs not the output, therefore cannot control the charging
• These inverters charge wide open and cannot taper off.
• A relay is required to disconnect the GT

What is AC Coupled ?
• SMA and Schneider use frequency shift to knock the GT inverter offline to stop the charging.
• The Sunny Island will control a Sunny Boy to do tapered charging.

What is AC Coupled ?
Generators and AC Coupled
• Radian and the Schneider have 2 AC inputs so a generator can be added.
• Provisions must be added to disconnect the GT inverter when the generator runs or the GT will try to sell to the Inverter.

Sizing Of The Off Grid Inverter
• Outback, Magnum and Schneider have a 1:1 ratio limit.
• SMA has a 2:1 ratio
• The customer may not need all of the grid tie solar as part of the ac coupled.

Outback FX series
• 120 vac per single unit.• Either Grid tie or Off Grid
not both. Both AC couple.• Grid tie models (G series)
does not play well with generators.
• Smaller scale and expandable.
• 12,24 and 48VDC models available
