400W Solar Kit for Workshops and Sheds with 3000W Inverter and 3.8kWh Storage

Turn your workshop or shed into a fully powered, grid independent workspace with this 400W Complete Solar Kit for workshops and sheds. Four high efficiency 100W N Type solar panels feed a 3.8kWh battery bank and a 3000W pure sine wave inverter, giving you clean AC power for lights, chargers, compressors, saws and other DIY tools without running extension cords from the house or listening to a generator all day.

Built around a 40A MPPT charge controller with advanced battery charging and full system protection, the kit is laid out for straightforward DIY installation so you can go from bare shed to powered shop in one go.

Solar Power Designed Around Real DIY Workloads

The 400W N Type array uses 16 bus bar, 100W panels with up to 25 percent cell efficiency, so they make the most of limited roof space on a shed or workshop. In good sun they keep your batteries topped up for typical shop loads: lights, chargers, small power tools, fans and task lighting.

A 3000W 12V pure sine wave inverter turns stored DC into grid like AC power, so sensitive tools and electronics run smoothly. That means everything from cordless tool chargers and laptops to small saws and shop vacs can plug into the system like a normal outlet, within the inverter’s rating.

Smarter Charging with 40A MPPT

At the heart of the charging side is a 40A MPPT solar charge controller using Renogy’s Maximum Power Point Tracking technology. With up to 99 percent tracking efficiency and peak conversion efficiency around 98 percent, it constantly adjusts to squeeze the most power from the panels, even when conditions change through the day.

That matters in cloudy or mixed weather where the maximum power point is moving. The 4 stage charging algorithm (bulk, boost, float, equalization where applicable) is tuned to extend battery lifespan by avoiding chronic undercharging or overcharging, which is especially important for a workshop setup that might see irregular use.

The controller auto detects 12V or 24V systems, accepts 15 to 100V DC solar input, and supports up to 520W on 12V or 1040W on 24V, leaving room to expand beyond the included 400W if you decide to grow the system later. It is protected against overcharge, over discharge, overload and short circuit, and can even recover some over discharged lithium batteries when configured correctly.

Two Battery Options: AGM or Pro Series LiFePO4

You can choose the storage that best fits how you use your workspace:

• Three 12V 100Ah Deep Cycle AGM Batteries
  A familiar, robust option if you want a simple, maintenance free lead acid setup. Each 100Ah AGM battery is rated for about 500 cycles at 50 percent depth of discharge, with a 10 hour capacity spec and a recommended charge voltage of 14.4 to 14.8V, float at 13.6 to 13.8V. They can be wired in series or parallel (up to 4 in parallel), and each weighs about 63.9 lb. This is ideal when weight is not critical and you want a straightforward, proven bank.
• Three 12V 100Ah Pro Series LiFePO4 Batteries
  For lighter weight and longer life, the Core Series lithium iron phosphate option brings a big upgrade. Each 12V 100Ah battery can deliver up to 5000 cycles at 80 percent depth of discharge, with a working voltage range from 10 to 14.8V, 100A max charge and discharge current, and 245A peak discharge for 30 seconds to start heavier loads. Housing is IP67 rated with UL94 V0 flame retardancy, and each unit weighs only about 26.9 lb. These batteries support parallel expansion up to eight units and include Bluetooth for app based monitoring.

Whichever you choose, three 100Ah batteries give you around 3.8kWh of nominal storage, enough to run typical workshop loads for a full working session when combined with daily solar production.

Built In Monitoring and Protection

The kit includes a 500A battery monitor with shunt, so you can see state of charge, current draw and consumption in real time instead of guessing from voltage alone. That makes it much easier to understand how your tools and lighting are impacting the bank and to avoid running batteries too low.

Fusing and cabling are correctly matched for a 3000W system:

• 40A ANL fuse set and 20A waterproof in line solar fuse holder for clean overcurrent protection
• 4AWG copper battery interconnect cables for linking batteries
• 8AWG ANL fuse cable and 10AWG tray cables and adaptor kit for controller and array runs
• Heavy battery to inverter cables for the 3000W inverter connection

These pieces give you defined protection points and reduce the risk of undersized wiring in a high draw workshop environment.

What Comes in the 400W Workshop / Shed Solar Kit

Every major component you need for a typical shed or workshop system is included:

• 4 × 100W 16BB N Type Solar Panels
• 1 × 40A MPPT Solar Charge Controller
• 3 × 12V 100Ah Deep Cycle AGM Batteries or 3 × 12V 100Ah Pro Series Deep Cycle Lithium Batteries
• 1 × 3000W 12V Pure Sine Wave Inverter
• 1 × Set of Solar Panel Mounting Z Brackets
• 3 × Solar Y Branch Connectors (MMF + FFM pairs)
• 1 × 20 ft 10AWG Solar Panel to Charge Controller Adaptor Kit
• 1 × 8 ft 10AWG Battery to Charge Controller Tray Cables
• 4 × 16 in 4AWG Copper Battery Interconnect Cables (5/16 in lugs)
• 1 × 1 ft 8AWG ANL Fuse Cable with Double Ring Terminals (3/8 in lugs)
• 1 × 40A ANL Fuse Set with fuse
• 1 × 20A Solar Connector Waterproof In Line Fuse Holder with fuse
• 1 × Set of Battery Inverter Cables (3/8 in lugs)
• 1 × 500A Battery Monitor with Shunt

Mount the panels on your shed roof with the Z brackets, run the pre cut cables to the controller and batteries, tie in the inverter and monitor, and you have a dedicated, self contained power system built specifically around a workshop or DIY shed.
