Backup and off-grid use
Built for properties that need stored energy, solar charging, and reliable AC output when grid power is limited or unavailable.
Simpler project planning
Helps reduce guesswork compared with sourcing panels, batteries, and inverter hardware separately.
A cleaner way to build a complete system
A complete solar power package saves time by bringing the major system pieces together around one goal: dependable stored power. It is built for customers who want a clearer path to an installed system instead of guessing through a long parts list.
- Built for customers planning a more complete solar and backup power system.
- Combines solar charging, lithium storage, and inverter output into one project-focused package.
- A strong fit for homes, cabins, farms, workshops, remote properties, and off-grid power builds.
- Helps reduce component-matching guesswork before installation.

Frequently Asked Questions
Clear answers to common questions about this product, setup, compatibility, and use.
Does the SGR-13KM package include the complete power train shown in its title?
The exact package is defined by the selected variant and its Package Includes list, centered on 13000W, 20.48KWH of battery storage, and 14 panels rated 415W each. Verify quantities for batteries, panels, controllers, cables, breakers, brackets, and racks before checkout because similar SunGoldPower kits use different component counts.
How should I build a load list for the SGR-13KM before purchase?
Do not size from nameplate watts alone. Add simultaneous continuous loads, then separately check startup demand and duration for compressors, pumps, motors, microwaves, and heating equipment against every inverter, leg, outlet, transfer, and battery-current limit.
What usable runtime should I expect from 20.48KWH in the SGR-13KM?
Build an hourly watt-hour load profile and compare it with usable battery energy after reserve, inverter loss, battery temperature, standby consumption, and aging. High-power appliances may fit the inverter yet consume the available 20.48KWH much faster than expected.
How much unshaded mounting area is needed for all fourteen SGR-13KM modules?
Daily harvest depends on site-specific peak sun hours, season, tilt, shade, snow, module temperature, wiring, and conversion loss. The string design must also keep cold open-circuit voltage, operating current, and tracker allocation inside the exact controller or inverter limits.
How should the two AC legs be balanced on the SGR-13KM's 13000W output?
The title identifies a 120V/240V system, but an installer must still verify per-leg limits, load imbalance, neutral and ground treatment, transfer equipment, breakers, conductor sizes, and which circuits belong in the backed-up panel.
