This 5.2kg 3kW RV Inverter Is 74% Lighter — And More Powerful
Picture this: You're upgrading your RV for the next season of travel. You've planned every detail — more storage, better comfort, smarter power. But then comes the inverter charger. Bulky, heavy, and complicated to install, it eats into your limited space, adds unnecessary weight, and turns a simple upgrade into a full-day wiring job.
That's exactly why we built the PH3.0L — the 3kW RV inverter charger that weighs just 5.2kg. It's 74% lighter than the typical market 3kW unit (which often tips the scales at 20kg). And it doesn't just save weight. It delivers more power, charges faster, runs quieter, and installs effortlessly.
Here's why this lightweight 3kW inverter charger is changing the game for RV owners who refuse to compromise on comfort.
PH3.0L vs. Typical 3kW Inverter Charger: The Numbers Don't Lie
| Feature | Typical 3kW Inverter Charger | PH3.0L Inverter Charger | What It Means for Your RV Life |
| Weight | 20kg | 5.2kg | 74% lighter — more payload for bikes & gear |
| Peak Power | 5.5kW | 6kW (2s) | 9% more surge — run AC + microwave + coffee maker together |
| Max Charging Current | 120A | 200A | 67% faster charging — back on the road sooner |
| Noise Level | Loud — transformer hum | ≤55dB — library quiet | Silent nights, peaceful RV living |
| Installation | Traditional terminals | WAGO plug-and-play | Tool-free and error-free installation |
Why Weight Matters More Than You Think in an RV
Every kilogram counts. Most RVs have a 3,500kg weight limit, and with water, fuel, gear and everything else loaded, you're often already close to that limit. The PH3.0L saves a full 15kg compared to a typical 20kg inverter — giving you more payload for your gear, bikes, and extra water tank. Its ultra-compact design fits neatly into tight compartments, so you finally get back valuable storage space without sacrificing any power or performance.
Power That Actually Keeps Up — Without the Bulk
You want to run the air conditioner, brew coffee, and heat up lunch in the microwave — all at the same time — without tripping the shore power breaker. The PH3.0L gives you 3kW continuous and 6kW peak pure sine wave power. That's 9% more surge than most inverters on the market, so your sensitive electronics stay happy and your appliances run smoothly.
Ultra-Fast 200A Charging = More Time Exploring, Less Time Waiting
Shore power is finally available after a long drive? The PH3.0L slams 200A into your batteries — 67% faster than the typical 120A unit. You're fully charged and ready for the next off-grid adventure while everyone else is still babysitting their slow chargers.
*Note: 200A charging requires a battery that supports ≥200A charge current.
Sleep Better with Library-Quiet Operation
No more transformer buzz or fan roar keeping you awake. Even at full load, the PH3.0L stays remarkably quiet at ≤55dB — true library-quiet performance. And it gets even quieter with two smart software-selectable modes:
- Silent Mode (Fan Off): The fan stays completely off, delivering ultra-quiet operation at ≤31dB with basically zero noise interference — perfect for boondocking when you want to hear the campfire crackle instead of your power system. It still supports up to 300W charging at 25°C.
- Quiet Mode (Min Fan): This is the noise reduction mode. The fan runs at its lowest speed, keeping noise to a gentle ≤43dB while allowing up to 2000W charging.
*Note: Noise levels are lab-tested. Real-world results may vary slightly based on installation environment, ambient temperature, and usage scenarios.
Error-proof Plug-and-Play Installation
The PH3.0L features plug-and-play AC WAGO connectors for both input and output. Simply strip the wire, insert it into the connector, align and push — it clicks securely into place. Fast, straightforward, and error-free.
First-time RV converters and weekend warriors love how simple and reliable the installation is.

Power Assist: Uninterrupted Power When Shore Power Falls Short
Shore power at campsites is often limited — sometimes as low as 10A. The PH3.0L’s Smart Power Assist automatically detects this and supplements power from your battery, so your air conditioner, coffee maker, and other appliances run smoothly without flickering or tripping the breaker.
Smart Monitoring: Full Control at Your Fingertips
No more wondering what's happening with your power system. With the PH3.0L, you can stay connected through the LIBER43 monitor and TBB app. Real-time updates, full visibility, and total peace of mind — so you can truly relax and enjoy the adventure.
