Hybrid Solar Inverters

2 Product Series · 11 Models available

Hybrid solar inverters combine a grid-tie inverter and a battery charger in one unit, so a single device can feed the grid, charge storage and supply critical loads when the grid fails. QDTB hybrid inverters cover 3 kW to 12 kW in low-voltage (48 V) and high-voltage battery platforms, with built-in MPPT, generator and grid ports. Seamless transfer to backup mode keeps essential circuits running during outages, while programmable operating modes enable self-consumption, peak-shaving and time-of-use arbitrage. They are the natural core of residential and small commercial solar-plus-storage systems.

Application Scenarios

Residential Solar-Plus-Storage

A single hybrid unit manages PV, battery and grid to maximise self-consumption of solar energy.

Backup Power

Automatic switchover to battery keeps lighting, refrigeration and communications alive during grid outages.

Time-of-Use Arbitrage

Charge the battery on cheap night-time power and discharge during expensive peak hours.

Off-Grid Homes

Build a complete island system from PV, battery and generator inputs without a separate charge controller.

Peak-Shaving for Small Business

Cap demand spikes from air-conditioning and machinery to reduce demand charges.

Grid-Tie with Future Storage

Install a hybrid now and add batteries later, avoiding a second inverter purchase.

Technical Advantages

All-in-One Architecture

MPPT charger, bidirectional inverter and transfer switch integrated in one enclosure.

Fast Transfer

Millisecond-grade switchover to backup mode keeps sensitive loads from rebooting.

Dual Battery Compatibility

Supports 48 V low-voltage or high-voltage LiFePO4 banks to match existing or planned storage.

Programmable Modes

Self-consumption, peak-shaving, UPS and generator-assist strategies selectable from the display or app.

Frequently Asked Questions

How is a hybrid inverter different from a string inverter?

A string inverter only converts PV to grid AC; a hybrid adds a battery port and backup output, so it can store energy and run loads off-grid.

What battery voltage should I choose?

48 V low-voltage suits retrofit and small systems with cheaper wiring; high-voltage banks reduce current and improve efficiency for larger storage.

How fast is the transfer to backup mode?

Our hybrids switch in milliseconds, fast enough that most computers and routers keep running without reboot.

Can I start with PV only and add batteries later?

Yes — the inverter operates as a grid-tie unit first, and the battery can be connected later without replacing hardware.

Does it support a generator input?

Yes, a dedicated generator port accepts a back-up genset for extended off-grid operation and battery charging.
