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.

Good hard use watch.
Color: Black/Silver-Tone
Review Calibration: 3 stars means it works as advertised, nothing special during use, and no amazing features. Higher stars mean better-than-expected performance and features. This is 5 stars because it is my favorite work/hard-use watch. I have been wearing one for years, and like all Timex watches, it can take a beating. I have to replace it when the band's ears get so damaged that they won't hold the band on. This has more to do with the plastic's lifespan than with a design issue. I am hard on watches. This watch normally lasts ne 7-10 years between replacements.

Typical Ironman quality
Color: Black/Silver-Tone
This is my fourth Timex Ironman watch. I own many watches, and prefer the Ironman for casual wear and sporting activities as well as swimming and snorkeling. I decided to replace an earlier model with this one rather than pay to change the battery. The Ironman has changed very little over the years since its introduction in the '80s, with the exception of cosmetic improvememnts and a larger display. I selected the "oversize" model as I was looking for a little more heft to this model. This watch fits the bill, not as chunky as my G-Shock. A pleasant surprise was the weight of the watch. This model is lightweight, another advantage over the G. It's larger than the typical Ironman model, but about the same weight. The band lacks the stiffness of some other Timex and Casio models, and is quite comfortable. Typical Ironman functions are unchanged, and the ability to "hide" various functions makes operation of the watch more efficient. There are three time zones, useful when traveling, as well as the usual chronograph/timer and alarm functions. I haven't worn the watch in the pool or ocean yet, but if experience is any guide, I expect no problems. I've never had an Ironman leak, whether during water sports or snorkeling. These are great watches for the money. I prefer 200 meter water resistance for this type of watch, but Timex has yet to build an Ironman 200m that doesn't overwhelm my wrist in weight and size. I'm not a big guy, and they are simply too large for my wrist. Looking forward to years of service with this watch. Definitely a good timepiece for the price.

Will not be disappointed
Color: Black/Blue
Keeping in mind that I received this item yesterday (2/24/16), I absolutely love this watch. The reason I have so much confidence with this watch is because I've owned one other Timex similar to this one, and it served me extremely well and is still able to do so. First off, this watch is certainly aesthetically pleasing. The blue color around the face of the watch and outline in the band, goes really well with the black frame. It's just an overall nice looking watch. More importantly, the quality seems great. As I mentioned, I've owned a Timex expedition, which I've had for more than 2 years, and it's still working perfectly fine. The watch seems like it's put together very well and there's no loose or flimsy parts. One complaint that many people seem to have with Timex is the quality of their band. Unfortunately I'd have to agree, since the band on my other Timex that's still working like the first day I got it, cracked and broke and is only being held together by the nylon fabric on the other side of the band. You're not going to have that problem with this watch. It's a full nylon band with Velcro adjustment, for precise fitting. it feels extremely comfortable and you won't need to worry about the band cracking (although I'm sure there will be certain defects in a mass produced bunch). I will use this watch for work and running, and rarely plan on taking it off. Just to give you an idea, I also have a garmin gps watch that I love and obviously has more functions than this watch. However, the second I received this watch, I slapped it on and put my garmin to the side. This watch also looks amazing when you wear it. I'll update this feedback as needed, but I'm confident this watch will serve me for years to come, just as my other one has.

Greatest watch I've ever had, but changing batteries is near impossible
Color: Black/Blue
This is the 3rd time I've bought this watch. Same brand, same or very similar model. It has a chronometer, timer, alarm, and of course the clock. It has something I think is for "occasions" but I don't know what it does and don't really care about it. The watch is durable. It uses battery power efficiently. The indiglo is second to none. I just really really like this watch. Having said all that, if you want to change the batteries, good luck, you'll need it. Once you manage to get the backing off of it and open it up (which is a little tricky in itself), it's like a comedy routine where you see some stooge open an electrical device and a buncha parts and springs go flying everywhere. And of course, they are so tiny, you'll never find them once they fly out. That was the exact scenario I found myself in the last time I tried to change the battery. It made me so mad I actually bought another brand of watch that I thoroughly researched. But that watch DIDN'T use battery power efficiently, and it had a host of other minor problems that added up to the conclusion that it was not nearly as great as this Timex. So, for the 3rd time, I found myself buying this Timex watch. So it's a wonderful watch in every way except longevity because changing the batteries has historically been a nightmare for me.
