Summer Sale

Summer Sale on Solar Kits, Inverters and Batteries: What to Buy Now

The summer sale collection gathers the complete off-grid and hybrid systems, split-phase inverters and server-rack batteries we are discounting this season. Summer is when most people install: panels go on a roof or ground mount in dry weather, and the system is charging before the shorter days and the first storms of fall. If you have been pricing a whole-home or cabin system, this is the collection to compare.

There are 82 products here, mostly Sungold Power kits plus the Rich Solar NOVA 12K inverter. Prices run from $1,690 for a 10,000W Sungold Power split-phase inverter to $18,878 for a 22.8kW hybrid kit with 51.2kWh of battery. Every kit ships with the inverter, batteries and panels matched by the manufacturer, so you are not guessing at compatibility.

How to choose from the sale

• Off-grid or hybrid. The SGR and SGM kits are off-grid: the Sungold Power 6,500W Off-Grid Kit SGR-6510E pairs a 6,500W split-phase inverter, 10.24kWh of LiFePO4 storage and eight 415W panels for a cabin, shop or RV pad. The SGH kits are hybrid with grid-tie capability, such as the Sungold Power 7.6kW 15.36kWh Hybrid Kit SGH-7.6N3E with twelve 500W panels. If you have utility service and want backup plus bill reduction, go hybrid.
• 120V only or 120/240V. The SGM-5K10M and SGM-655M kits output 120V, which suits a small cabin without 240V appliances. The SGR-6510E, SGR-15K20E and every SGH kit output 120/240V split-phase for a full breaker panel.
• Battery hours. The 5.12kWh in the SGM-655M covers an evening of lights, fridge and electronics. The 30.72kWh in the SGH-11N3E or the 51.2kWh in the SGH-11N5E carries a whole house through a cloudy stretch.
• Buying components instead. If you already own batteries or panels, the sale also lists the Sungold Power 10,000W split-phase inverter, the Rich Solar NOVA 12K hybrid and a four-pack of SG48100P server-rack batteries totaling 20.48kWh.

Sizing tips

• Run the Solar Kit Calculator with your appliances and ZIP code before picking a kit. Summer sun hours overstate what you will get in December, and the calculator accounts for that.
• Count roof or ground space. Thirty-two 415W panels, as in the 16,000W SGR-16K25E, need far more area than the six 370W panels in an SGM kit. Measure before you order.
• Sale kits with a price range, like the SGH-7.6N3E from $5,874, offer more battery or panel options at checkout. Pick the battery size first; panels are easier to add later.
• Plan the inverter location now. Wall-mounted split-phase inverters and server-rack batteries need a dry, ventilated space near the main panel.
• If the kit is for a well pump or shop tools, confirm 240V output. The 120V SGM kits will not start them.

Frequently asked questions

Are sale kits the same as full-price kits? Yes. They are current models with the same components and the same manufacturer support; the discount is seasonal.

Can I expand a kit later? The SGM-5K10M and SGM-5K5E are described as customizable with extra batteries and panels. The dual-inverter kits like the SGR-16K25E already run two paralleled inverters, which is the same path you would use to grow a single-inverter kit.

What does a 10.24kWh battery actually run? A fridge, lights, a TV and a laptop overnight, with room for a microwave or coffee maker in the morning. Air conditioning through the night needs the 25.6kWh or larger kits.

Everything ships free to the mainland US from our brand partner warehouses, usually within a few business days, with 30-day returns. If you are torn between two kits, call and we will work through your load list together.
