People are asking

What can a 3000W inverter/charger run in a campervan?

A 3000W pure sine wave inverter/charger can run most 240V household appliances including a kettle, microwave, toaster, hairdryer, air conditioner, and battery chargers simultaneously. It also acts as a battery charger when connected to shore power, making it an all-in-one power management solution.

What battery bank size do I need for a 3000W inverter?

At 3000W on 12V the inverter draws up to 250A from the battery bank. You need a battery with sufficient continuous discharge capability — a 200Ah or larger lithium battery is recommended, ideally 400Ah for meaningful runtime. Cable sizing and fusing at this current is critical — use appropriately rated battery cable and a 350A ANM fuse.

Does the Projecta 3000W unit charge from both solar and mains?

Yes. The Projecta 3000W 12V Inverter/Charger manages both 240V mains charging when on shore power and integrates with solar input via a compatible MPPT controller. It provides a complete power management solution for full-time van life or motorhome use.
