Solar Power Kits Sale

Solar Power Kits Sale: Where the Money Goes and What to Buy at Each Budget

This page gathers the solar power kits currently on sale at Eco Solar Kits, sorted so you can compare what a given budget actually buys. A kit here means matched components sold as one order: at minimum a battery and inverter that are confirmed to work together, and in many cases the panels as well. Buying matched gear avoids the most common expensive mistake in DIY solar, which is pairing a battery and inverter that cannot talk to each other.

The sale collection holds 112 products from Sungold Power, EG4, BigBattery (HUSKY 2 and NEXUS), Victron, Bluetti and Anker. Prices run from $899 for a 2,600W portable station to $15,725 for a 16,000W split-phase system with 25.6kWh of storage and thirty-two panels.

How to choose a kit on sale

• Decide what the kit must include. Complete packages such as the Sungold Power 8,000W Off-Grid Kit ship with 8 x 415W panels, a 10.24kWh battery and the inverter, from $5,518. Battery-plus-inverter pairs like the NEXUS 14.3kWh + EG4 6000XP leave panel choice to you, which is the better route if you already own modules or want a specific roof layout.
• Continuous output. A cabin with a well pump and a small mini-split sits comfortably on 5,000 to 6,500W. A full-size home with an electric range or dryer wants 10,000W or more, which is why the EG4 PowerPro 12kW 28.7kWh exists at $8,685.
• Storage in kWh. 5.12kWh covers lights, fridge and electronics overnight. 10 to 14kWh handles a small home. 25kWh and up is for going fully off-grid in a cloudy climate.
• Mobile or fixed. The HUSKY 2 5.12kWh + Victron MultiPlus-II 3,000W is built for RVs and vans, with PowerAssist that lets the battery supplement a weak shore hookup. The EG4 and NEXUS systems are indoor or wall-mount installs for a building.
• Grid-tied or off-grid. Most kits here are off-grid. The EG4 WallMount 16kWh with FlexBOSS21 is the grid-tied option, with up to 21kW of solar input across 3 MPPT trackers.

Sizing tips

• Start with the Solar Kit Calculator. Enter your appliances and ZIP code and it returns battery, inverter and panel targets, so you can filter this sale page to kits that clear all three.
• Do not buy on inverter watts alone. A 6,500W inverter with 5.12kWh of battery empties in under an hour at full load; match storage to how long the loads run, not just how big they are.
• Check the output type. A 120V-only inverter such as the Victron MultiPlus-II in the HUSKY 2 kits cannot run a 240V well pump or dryer; the SGR series and the EG4 6000XP deliver split-phase 120V/240V.
• Leave room to grow. The NEXUS systems scale to 214.5kWh on the same platform, and the Elite 200 V2 accepts B80, B230 or B300 expansion packs, so a smaller purchase now is not a dead end.
• Sale pricing changes as partner stock moves, so if a kit fits your numbers today it is worth ordering rather than waiting on a further drop.

Frequently asked questions

Is a sale kit different from the regular version? No. These are the same products at a reduced price, shipped from the same brand partner warehouses with the same 30-day return window.

Do the panel-free kits need anything else to work? Yes: panels, PV wiring and, for a home install, an electrician for the AC side. The battery and inverter arrive pre-matched with closed-loop communication already set up.

Which kit is the cheapest way to back up a fridge and lights? The Bluetti Elite 200 V2 at $899 stores 2,073.6Wh and delivers 2,600W, enough for a refrigerator, router and lights through a typical overnight outage.

Every kit ships free to the mainland US, usually within a few business days. If two options look close on paper, call us and we will walk through the trade-offs for your house or rig.
