Rich Solar MEGA 100 Portable Briefcase Charging Kit — 100W 12V Complete Solar Kit
The MEGA 100 Portable Briefcase Charging Kit is everything you need to start charging a 12V battery from solar — right out of the box. The same compact, 15.7 lb folding briefcase panel paired with a waterproof 10A PWM solar charge controller, pre-wired and ready to connect directly to any 12V battery type: lithium, AGM, GEL, or flooded. No sourcing a separate controller. No compatibility guesswork. Just unfold, connect, and charge.
What's Included in the Kit
Complete System — Nothing Else to Buy
Panel and charge controller are matched, pre-wired, and ready to connect directly to your 12V battery. No separate controller purchase, no compatibility research, no additional wiring — add a battery and you have a fully operational portable solar charging system.
Charges All 12V Battery Types
The included 10A waterproof PWM controller supports lithium, AGM, GEL, and flooded lead-acid 12V batteries — covering virtually every battery type used in RV, marine, off-grid cabin, van, and emergency preparedness applications.
Folds to 25.2 × 18.1 in, 15.7 lbs
The entire kit travels as one compact unit — panel and controller fold together into a package small enough to store behind a vehicle seat, in a truck bed corner, or in an RV storage bay. Deploy the kickstand wherever the sun is and start charging within a minute.
Product Overview
The Rich Solar MEGA 100 Portable Briefcase Charging Kit is the complete-system version of the MEGA 100 Briefcase Panel — built for buyers who want to go from zero to charging a 12V battery without sourcing, sizing, or wiring a separate charge controller. The kit pairs the same compact 100-watt monocrystalline briefcase panel with a 10A waterproof PWM solar charge controller that's pre-matched to the panel's output and ready to connect directly to a 12V battery bank.
The 10A controller handles the full output of the 100W panel at 12V with headroom to spare, protecting the battery from overcharge while optimizing the charging profile for the battery type in use. PWM controllers deliver a consistent, proven charging method for lead-acid battery chemistries — AGM, GEL, and flooded — and are also confirmed compatible with lithium 12V batteries, making this kit a practical match for the most common battery types used in RVs, boats, cabins, vans, and emergency preparedness setups.
For buyers who are new to solar and don't want to research controller sizing, wiring gauges, and compatibility before making a purchase, the kit removes all of that friction. For experienced solar users who want a self-contained portable system to take on trips without relying on a power station, the kit delivers a complete, weatherproof, briefcase-portable charging rig that connects to any 12V battery they already own.
Why the Kit vs the Panel Alone
- Controller Included, Pre-Matched: The 10A PWM controller is sized and pre-matched for this exact panel — no guesswork on amperage rating, voltage compatibility, or wiring setup.
- Supports All 12V Battery Types: Lithium, AGM, GEL, and flooded lead-acid — select the battery type on the controller and connect. No additional programming or adapters required for the most common 12V battery chemistries.
- Waterproof Controller: The included controller is rated for outdoor and exposed installation — mounts to a battery box, a boat transom, or an RV interior panel without needing additional weatherproofing.
- Overcharge Protection Built In: The controller automatically regulates charging voltage and current to prevent battery overcharge — critical for unattended charging on camping trips, extended outdoor use, and emergency setups.
- One Purchase, Ready to Use: Add any 12V battery and you have a fully operational portable solar charging system — no additional components, no additional trips to a solar supply store.
100W Panel Built for Portable Life
- Folds to 25.2 × 18.1 × 2.4 in: Compact enough to fit behind a vehicle seat, stand in a truck bed corner, store under a boat seat, or slide into most RV storage bays — the most portable size in the MEGA briefcase lineup.
- Built-In Adjustable Kickstand: Prop the panel at an optimal sun angle on any flat surface — campsite, dock, parking lot, tailgate, or boat deck — without external support hardware.
- Corner Protection on All Edges: Reinforced corners protect the frame and glass through repeated folding, travel, and storage across the life of the kit.
- Tempered Glass + Aluminum Frame: Rigid, fully weatherproof construction — significantly more durable than fabric folding panels for a kit that gets deployed and stored repeatedly over years of use.
- Monocrystalline Cells: High-efficiency mono cells deliver strong output including on overcast days, in morning and evening hours, and in varying cloud-cover conditions — reducing daily charging dead time.
Direct 12V Battery Charging — No Power Station Needed
- Charges Lithium 12V Batteries: LiFePO4 and lithium batteries used in RVs, vans, marine installs, and off-grid setups — compatible with the included PWM controller's lithium charging profile.
- Charges AGM Batteries: The most common sealed lead-acid chemistry in RV house banks, marine batteries, and off-grid backup systems.
- Charges GEL Batteries: Often used in deep-cycle marine, wheelchair, and solar backup applications — correctly managed by the PWM controller's GEL profile.
- Charges Flooded Lead-Acid Batteries: Traditional wet-cell batteries used in agricultural, farm, and older marine and RV applications.
- Overcharge & Over-Discharge Protection: Controller manages the full charge cycle automatically — including float mode to maintain battery health without overcharging during extended sunny periods.
The Right Starting Kit for Off-Grid Beginners
- First Solar System: For anyone buying their first off-grid solar setup, the kit eliminates the most common mistakes — undersized controllers, mismatched battery types, and incorrect wiring — by providing a complete, pre-matched system.
- Camping & Overlanding: Keep a 12V house battery, a portable jump starter, or a deep-cycle AGM topped off during a weekend trip without relying on hookups or a generator.
- Fishing & Boating: Charge a marine starting battery or a trolling motor AGM directly from the panel while docked or beached — no shore power required.
- Emergency Preparedness: A complete portable solar charging kit stored in a garage or vehicle that deploys in minutes to charge a backup battery bank during grid outages.
- Van & RV Supplemental Charging: Deploy outside when rooftop panels aren't getting enough direct sun — angle toward the sun while parked and feed a 12V house bank directly through the included controller.
