1980W 48V Off-Grid Solar Kit – Magnum MS4448PAE, PT100, MMP175-30D


SKU: KIT-1980-48-MINI Category:

We built this 1980W 48V Off-Grid Solar Kit with a Magnum MS4448PAE inverter, wiring Mini Panel, and PT-100 charge controller to store solar energy in 48 Volts DC and deliver 4,000W of pure sine wave power at 120 or 240 Volts AC. The system comes with all the necessary components and accessories, and the installation is simple:

a) Wire the Magnum MS4448PAE inverter/charger onto the MMP175-30D Magnum Mini Panel enclosure, attach the PT-100 charge controller (included).

b) Additionally, pair the power center with the 6 monocrystalline solar panels for a total of 1,980 Watts of PV power; the system comes with the MC4 cables, combiner box, and breakers required to string the solar panels at the optimal voltage.

c) Last, interconnect the 8 batteries in series using the 7 cables provided to reach 48VDC; connect the pos/neg output cables (also provided) to the DC terminals in the power center; the Mini Panel enclosure comes with a 175A main DC disconnect breaker.

With the MPPT charge controller, you will fully recharge the battery bank in one sunny day (estimated at five peak sun hrs). We sized the battery bank to operate at 50% depth of discharge (DOD) and comfortably support the expected energy demand of the system.

The Magnum MS4448PAE inverter functions as an AC battery charger as well; use Magnum’s ME-AGS-N Automatic Generator Start to have a fuel-based generator automatically start and support larger loads or complement the PV system when production is low.

Note: this kit does not come with the rails and hardware to mount the solar panels; please call us to evaluate your project requirements.
