Ph Fax Off Grid. Battery Based Grid Tie. AC Coupled. All of MidNite Solar’s Pre Wired systems are fully customizable for your needs

Stand alone system Will not sell back to the utility Various inverters available for Off Grid (Some will do both) 120 or 120/240? Ph Fax

Sells to the grid Runs critical loads during grid failure Do you need 120vac or 120/240vac Some models support generator input as well Ph Fax

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. Ph Fax

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

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. Ph Fax

Not all battery based sinewave inverters are capable of back feed. Your choices in North America are: SMA Sunny Island Outback FX, VFX and Radian Magnum PAE series Schneider XW series Ph Fax

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 Ph Fax

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. Ph Fax

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. Ph Fax

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. Ph Fax

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 Ph Fax

Grid tie or Offgrid Supports both AC coupled as well 120/240 in a single unit Has 2 AC inputs (2nd for generator) 8,000 watts per unit, Stackable 48VDC model Requires relays for AC coupled Ph Fax
