Renogy 400-Watt 12-Volt Solar Complete Kit w/ 2 Packs of 12-Volt 100Ah Deep Cycle AGM Battery

The Renogy 400W 12V Complete Solar Kit with two 100Ah AGM batteries (RKIT400DAP2) is a full system in one order: four 100W 16BB N-Type panels, a Rover Li 40A MPPT charge controller, two 12V 100Ah deep-cycle AGM batteries, a 2000W pure sine wave inverter, a 500A battery monitor with shunt, and the wiring, mounting, and fusing to connect all of it. Nothing else is required to produce, store, and use 120V AC power off-grid.

Who This Kit Is For

This is the right kit for a first complete system on a garden shed, hunting cabin, camper, or RV, especially if you want the lower upfront cost of AGM batteries and your site rarely demands deep daily cycling. AGM is honest old technology: maintenance-free and tolerant of cold storage, but you should only plan on using about half of its rated capacity per cycle, and the two batteries weigh 63.9 lb each per Renogy. If you will cycle the bank hard every day, or if weight matters, the lithium version of this same kit stores the same nominal energy with far more usable capacity per cycle.

Key Features

• Complete system: panels, controller, batteries, inverter, monitor, cables, mounts, and fuses in one kit, matched by Renogy
• Four 100W 16BB N-Type panels; 10-year material and workmanship plus 25-year power output warranty, per Renogy's datasheet
• Rover Li 40A MPPT controller (max PV input 520W at 12V, per Renogy) leaves about 120W of expansion headroom
• Two 12V 100Ah deep-cycle AGM batteries, about 2,400Wh nominal storage
• 2000W pure sine wave inverter with 4000W peak, per Renogy, runs microwaves, coffee makers, and power tools one at a time
• 500A battery monitor with shunt included, so you see real state of charge instead of guessing from voltage
• BT-2 Bluetooth module included for monitoring in the Renogy app
• Per Renogy, the system generates 2,000 to 2,500Wh daily, based on 5 to 6 peak sun hours per day

Why Renogy

Renogy has specialized in off-grid systems since 2010 and pre-matches every component in this kit, panel voltage to controller window, controller to battery profile, inverter cabling to battery bank, which is most of the engineering in a small install. Documentation and app support are published for every piece.

What Will It Run?

Renogy's published estimate is 2,000 to 2,500Wh per day at 5 to 6 peak sun hours. Our more conservative planning figure: 400W x 4 h x 0.75 = roughly 1,200Wh per day for northern or winter conditions. On the storage side, plan around 50% depth of discharge for AGM longevity: about 1,200Wh usable per full cycle.

• Steady loads: LED lights (75Wh) + 12V fridge (about 1,100Wh/day) fits the sunny-day harvest but will draw the bank down across cloudy days, so a fridge is realistic in good sun regions, marginal in gray winters.
• Short heavy loads: the 2000W inverter runs a 900W microwave for 10 minutes (about 150Wh) or a 1,200W coffee maker for 6 minutes (about 120Wh) without strain; avoid running two large appliances at once.
• Not for this kit: air conditioning, electric heat, and well pumps with high starting surges exceed sensible sizing at 400W of solar.

All figures are estimates with stated assumptions.

Warranty & Support

Per Renogy: panels carry a 10-year material and workmanship plus 25-year power output warranty (datasheet); Rover series controllers carry a 3-year material and workmanship warranty; and Renogy's 12V 100Ah AGM batteries carry a 2-year prorated warranty under Renogy's published limited warranty policy.

Shipping

Ships within the United States. This kit is heavy, the two AGM batteries alone are about 128 lb combined, and it arrives as multiple cartons, sometimes on different days or by different services. Inspect batteries and panel faces on delivery and note any damage with the carrier; questions, call (302) 496-3554.

Frequently Asked Questions

Can I add panels later?

A little. The Rover Li 40A accepts up to 520W at 12V per Renogy, so there is room for one more 100W panel above the included 400W. Beyond that, you would upgrade the controller or move to a 24V design.

AGM or lithium, honestly?

AGM wins on upfront cost and cold storage tolerance; lithium wins on usable capacity (80%+ vs about 50% depth of discharge), cycle life, and weight (the lithium version's batteries are 26.9 lb vs 63.9 lb each, per Renogy). Weekend and backup use favors AGM economics; daily full-time cycling favors lithium.

Can I upgrade to lithium batteries later?

Yes. The Rover controller has a lithium profile, so you can swap the bank down the road, for example to a single Core 12V 300Ah self-heating LiFePO4, and keep the rest of the kit. Do not mix AGM and lithium in one bank.

Roof or ground mount?

Z-brackets are included for flat mounting on an RV, shed, or cabin roof. For ground mounting, add a tilt rack; a steeper winter angle helps a 400W array noticeably.

Can this combine with my RV's alternator?

Yes, by adding a separate DC-DC charger between the starter battery and this bank. The included Rover controller handles the solar side only.

Do I need any electrical experience to install it?

The kit is designed for DIY: pre-terminated cables, included fusing, and Renogy's manuals. Comfort with basic DC wiring and torqueing lugs is enough for most installs; call us if you get stuck mid-install and we will talk you through it.

What if my loads are bigger than this kit?

Step up in array, storage, or both; see the Renogy collection for 600W and 800W kits and larger battery banks.
