Baintech BT2000W 2000W Inverter Charger with Remote Control

Two-in-one solution—powers your gear and charges your batteries from mains or generator when available.

Product Overview

The Baintech BT2000W is a 2000-watt inverter charger that combines AC power conversion with intelligent battery charging in one compact unit. Unlike standalone inverters that only convert DC to AC, this unit automatically switches between inverter mode when running off batteries and charger mode when connected to mains power or a generator, seamlessly managing power flow in both directions without manual intervention.

Built around pure sine wave technology, the BT2000W delivers grid-quality 240V AC power suitable for sensitive electronics including laptops, medical devices, audio equipment, and appliances with microprocessor controls. The 4000W surge capacity handles motor starting loads from fridges, pumps, and power tools that require brief high-current draws on startup.

The integrated battery charger supports four-stage charging (Bulk, Absorption, Float, Recharge) across multiple battery chemistries including AGM, flooded lead-acid, gel, and lithium. The included remote controller allows convenient power management and monitoring from accessible locations without accessing the main unit. Ideal for caravan installations, off-grid cabins, marine systems, and mobile workshops where both reliable AC power and efficient battery charging are essential.

Features & Benefits

Dual Function Inverter/Charger: Eliminates the need for separate inverter and battery charger units, saving space, weight, and wiring complexity. When connected to mains power or generator, it automatically switches to charge mode and passes AC through to loads while simultaneously charging batteries. When mains power disconnects, it instantly switches to inverter mode drawing from batteries. Perfect for caravan sites with intermittent power or workshops alternating between generator and battery operation.

2000W Pure Sine Wave Output: Delivers clean, grid-quality power suitable for all equipment including sensitive electronics, audio systems, laser printers, variable speed tools, and medical devices. The pure sine wave prevents the buzzing, overheating, and premature failure that modified sine wave inverters cause in motorized loads and microprocessor-controlled equipment.

4000W Surge Capacity: Handles brief high-current draws from equipment startup. Fridges, air compressors, pumps, and circular saws require 2–3× their running wattage for motor starting. The 4000W surge capability covers these startup loads without tripping protection circuits, allowing equipment to start reliably even when running at full 2000W continuous load.

Multi-Chemistry Battery Charging: The intelligent four-stage charging system adapts to gel, flooded lead-acid, AGM, and lithium batteries. Each chemistry requires different voltage profiles and charging algorithms—the BT2000W handles this automatically, protecting battery investment and maximizing lifespan regardless of your battery choice. Critical for systems upgrading from lead-acid to lithium without replacing charging infrastructure.

Remote Controller Included: Mount the remote control panel in accessible locations—inside the cabin, at the camp kitchen, or anywhere convenient. Monitor input/output voltage, battery status, charging progress, and power mode without accessing the main unit installed in battery compartments or under-seat locations. Switch between inverter/charger modes and adjust settings from the driver's seat.

Automatic Transfer Switching: Seamlessly switches between mains/generator power and battery power with no manual intervention. When you plug into powered sites, it automatically charges batteries and passes AC through to appliances. When you unplug, it instantly switches to inverter mode. No gap in power to equipment, no manual changeover switches to operate.

Advanced Battery Management: Four-stage charging (Bulk, Absorption, Float, Recharge) optimizes battery charging regardless of chemistry. Bulk mode delivers maximum current until batteries reach approximately 80% charge, Absorption mode completes charging at controlled voltage, Float mode maintains full charge without overcharging, and Recharge mode detects when batteries need topping up. This prevents the overcharging damage common with basic chargers.

High Efficiency at 87%+: Minimizes battery drain and heat generation. At 87% efficiency, only 13% of power is lost as heat during conversion, critical for installations in enclosed spaces where heat dissipation is limited. More efficient operation means longer battery runtime and less load on cooling systems.

Comprehensive Safety Protection: Over-voltage protection prevents damage from alternator voltage spikes or incorrect charging sources. Under-voltage protection prevents deep battery discharge that damages cells. Overload protection prevents damage from excessive current draw. Over-temperature protection prevents thermal damage during sustained high loads. Short-circuit protection prevents catastrophic failure from wiring faults.
