Product Description

The Jackery HomePower 3600 Pro Max is a 3584Wh portable power station built on LFP (LiFePO4) cells rated for 6000 charge cycles while retaining at least 70% of their original capacity. Its inverter delivers 4000W of continuous output with an 8000W peak surge and is dual voltage, pairing two 120V outlets with a US split-phase 240V NEMA 14-50 outlet for high-draw equipment. Capacity starts at 3.6kWh and expands up to 21.5kWh on a single unit with Battery Pack 3600 modules, so this is backup power that can grow with your household.

Who It's For

The HomePower 3600 Pro Max suits homeowners who want substantial backup power without a permanent installation, off-grid property owners who need 240V capability, and anyone whose essential equipment runs from a NEMA 14-50 outlet. It is also built for whole-home-style setups: the 9.6kW high-power bypass and 50A split-phase AC input socket make it suited to a 50A split-phase manual transfer switch (240V). Transfer switches should be installed by a licensed electrician, and when circuits run from the battery, keep the combined load within the 4000W inverter rating — exceeding it can cause an overload shutoff.

Key Features

3584Wh LFP battery – LiFePO4 chemistry rated for 6000 cycles to at least 70% capacity, designed for regular use rather than occasional emergencies
4000W rated output, 8000W peak surge – dual-voltage 120V/240V output: one US split-phase 240V NEMA 14-50 outlet rated at 4000W plus two NEMA 5-20R 120V outlets at 2000W each
Expandable from 3.6kWh to 21.5kWh per unit – uses the common Battery Pack 3600 module; parallel connection supports up to 8000W of output, and a cascaded/parallel system can reach up to 43kWh of storage
Built-in 9.6kW high-power bypass – 50A split-phase AC input socket with support for automatic switching between generator power and battery storage
UPS switchover in 10ms or less – battery output takes over quickly when grid input drops
Fast recharging – 1800W AC input (120V 60Hz) for a roughly 2.5-hour recharge, or up to 1200W of solar input for a roughly 4-hour solar recharge
Quiet charging – silent-mode charging at 30dB or less
USB charging built in – one 100W USB-C (PD) port and one 18W USB-A port
App support and LCD display – monitor status and control the station from the built-in display or the app

Why Jackery

Jackery builds the HomePower series around LFP (LiFePO4) chemistry, a battery type chosen for long service life and stability — the 6000-cycle rating on this station works out to years of regular cycling, not just standby duty. Just as important is the system design: because the Pro Max expands with the common Battery Pack 3600 module, capacity you add today stays useful as your setup grows toward parallel output of up to 8000W and up to 43kWh of storage. And like every Jackery product we carry, the 3600 Pro Max is backed by Jackery's manufacturer warranty.

Frequently Asked Questions

Can the HomePower 3600 Pro Max run 240V appliances?

Yes. It is dual voltage, with a US split-phase 240V NEMA 14-50 outlet rated at 4000W alongside two 120V NEMA 5-20R outlets at 2000W each. Total draw is limited by the 4000W rated inverter, with 8000W available for brief startup surges.

Can I connect it to my home's circuits with a transfer switch?

The station is suited to a 50A split-phase manual transfer switch (240V) setup, using its built-in 9.6kW high-power bypass and 50A split-phase AC input socket. A licensed electrician should install the transfer switch. When circuits are running from the battery, keep the combined load within the 4000W inverter rating — exceeding it can cause an overload shutoff.

How do I expand the capacity?

Add Battery Pack 3600 modules to grow from 3.6kWh up to 21.5kWh on a single unit. Parallel connection supports up to 8000W of output, and a cascaded/parallel system can reach up to 43kWh of total storage.

How fast does it recharge?

From a 120V 60Hz wall outlet it accepts 1800W and recharges in about 2.5 hours. With up to 1200W of solar input, a full solar recharge takes about 4 hours.

How long will the battery last?

The LFP (LiFePO4) battery is rated for 6000 cycles while retaining at least 70% of its original capacity, so it is built for regular daily cycling as well as emergency backup.

Does it work as a UPS?

Yes. When grid input drops, the station switches to battery output in 10ms or less.

Can it work together with a generator?

Yes. Through the high-power bypass input, the system supports automatic switching between generator power and battery storage.

What comes in the box?

The Jackery HomePower 3600 Pro Max, an AC charger cable, and a user manual.
