Renogy 400-Watt 12-Volt Solar Farmer Kit w/ 3 Packs of 12-Volt 100Ah Lithium Iron Phosphate Battery

The Renogy 400W 12V Solar Farmer Kit with lithium storage is a complete off-grid package: four 100W 16BB N-type solar panels, a Rover Li 40A MPPT charge controller, three 12V 100Ah deep-cycle lithium iron phosphate batteries, a 3000W 12V pure sine wave inverter, and a 500A battery monitor with shunt — plus brackets, cabling, and fusing. Per Renogy, it is designed for workshops, sheds, and DIY off-grid power projects. OffGrid Horizon is a family-owned authorized Renogy dealer serving the US market.

Who This Kit Is For

Choose this version over the AGM configuration if you'll cycle the batteries regularly: the LiFePO4 bank is rated for 5,000 cycles at 80% depth of discharge per Renogy — ten times the cycle life of the AGM alternative — and each battery weighs 26.9 lb versus 63.9 lb for AGM. That makes it the pick for a shop, barn, or outbuilding you use most days, or anywhere you want more usable energy from the same 3.6kWh nominal bank.

Key Features

• Complete kit: panels, charge controller, lithium storage, inverter, battery monitor, and connection hardware in one order.
• 400W solar array: four compact 100W 16BB N-type panels; N-type cells rated up to 25% cell efficiency, per Renogy.
• 3.6kWh LiFePO4 bank: three 12V 100Ah deep-cycle lithium batteries rated 5,000 cycles at 80% DOD; per Renogy's kit listing they feature Bluetooth communication and an IP67-rated housing.
• Rover Li 40A MPPT charge controller: 12V/24V auto-recognition, up to 100VDC PV input, lithium charge profiles supported, per Renogy.
• 3000W pure sine wave inverter: 120V/60Hz output with 6,000W surge for motor starts, per Renogy.
• 500A battery monitor with shunt for true state-of-charge tracking.
• Fusing included: 40A ANL fuse set, ANL fuse cable, and waterproof in-line fuse holder.

Specifications

What Will It Run?

Stated assumptions: estimates assume 4.5 peak sun hours per day (mid-range US annual average; regional values roughly 3.5 to 5.5), 25% combined system losses, and lithium discharge to 80% DOD per Renogy's cycle rating. Appliance wattages are typical estimates.

• Estimated daily solar harvest: 400W x 4.5 h x 0.75 ≈ 1.35kWh per day under those assumptions.
• Usable storage: roughly 2.9kWh at 80% DOD — about two days of reserve at the harvest estimate, and 60% more usable energy than the AGM version of this kit.
• Example workshop day (~1.2kWh): LED shop lights (~0.2kWh), cordless tool charging (~0.3kWh), a fan and radio (~0.2kWh), plus about 25 minutes of saw or compressor run time (~0.5kWh).
• Limits: the inverter supports 3,000W continuous, but a sustained 3,000W load would empty the bank in under an hour — heavy tools are for bursts, not all-day duty.

Warranty & Support

Per Renogy: rigid panels carry a 10-year material and workmanship warranty with tiered power output coverage (95% at 5 years, 90% at 10 years, 80% at 25 years); Renogy's deep-cycle lithium batteries carry a 5-year prorated material and workmanship warranty; the 3000W inverter carries a 1-year material and workmanship warranty. Remaining components carry Renogy's standard limited warranty. Call our family-owned shop at (302) 496-3554 with questions before or after purchase.

Shipping

This kit ships as multiple heavy cartons and typically travels LTL freight on a pallet within the US. The carrier will schedule delivery; a liftgate is standard for residential stops. Inspect all cartons before signing the delivery receipt, note any damage or shortage on the receipt, and contact us right away so we can resolve it with the carrier.

Frequently Asked Questions

What do I gain over the AGM version?
Per Renogy's ratings: 5,000 cycles at 80% DOD versus 500 cycles at 50% DOD, roughly 2.9kWh usable versus 1.8kWh from the same nominal bank, and 37 lb less weight per battery. AGM's advantages are lower up-front cost and simple cold-weather storage.

Can the batteries charge in freezing weather?
These are standard (non-heated) LiFePO4 batteries, and lithium cells must not be charged below freezing; the BMS provides protection. Plan an insulated or heated battery location for winter charging, or ask us about Renogy's self-heating battery options.

Can I expand the battery bank later?
Renogy supports paralleling matching batteries. If you already know you'll need much more storage, it's cleaner to plan the bank up front — for example around the Renogy 4-pack 12V 300Ah LiFePO4 batteries — rather than mixing models later. Call us and we'll help you plan.

Can I add more solar?
Modestly — per Renogy the Rover Li 40A accepts up to 100VDC input, and its power ceiling on a 12V bank leaves limited room above 400W. Talk to us before buying extra panels.

Will it start my compressor or table saw?
The 6,000W surge rating per Renogy handles most small and mid-size shop motors; check your tool's startup draw to be sure.

What does the 500A shunt monitor do?
It counts amp-hours in and out at the battery terminal, giving an accurate state-of-charge display — more reliable than voltage readings, and a good cross-check alongside the batteries' Bluetooth data.
