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.
What major equipment is included in the SGR-12K20E solar kit?
The exact package is defined by the selected variant and its Package Includes list, centered on 12000W, 25.6KWH of battery storage, and 12 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.
Can the SGR-12K20E's 12000W inverter start every appliance below that wattage?
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.
How long can the SGR-12K20E's 25.6KWH battery supply my critical loads?
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 25.6KWH much faster than expected.
Is the SGR-12K20E's 12 panels rated 415W each array enough to refill the batteries in one day?
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.
Can the SGR-12K20E serve 120V lighting and a 240V pump from the same backup panel?
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.
