LuxpowerTek LXP ACS 3600 MG (AC-coupled Inverter)

Turn any on-grid or micro-grid solar system into a fully optimised energy storage setup.

The LXP ACS 3600 is a 70A AC-coupled retrofit inverter built to add battery storage, smart tariff optimisation, seamless backup power, and scalable expansion to existing systems.

It works alongside your current solar inverter, supports up to 8 units in parallel, includes a dedicated EPS port for flexible load management, and intelligently charges around Octopus time-of-use tariffs and weather forecasts.

Designed for Retrofit Applications

The LXP 3600 ACS installs on the AC side of an existing system and works alongside your current grid-tied inverter. Enabling you to;

• Add 48V battery storage to existing solar installations
• Charge batteries from low-cost grid periods
• Store excess solar generation via the existing inverter
• Discharge during peak-rate windows to reduce import costs
• Maintain essential loads during grid outages

This architecture makes it ideal for upgrading operational solar systems without full system redesign.

Optimised for Time-of-Use Tariffs

The LXP 3600 ACS supports intelligent charging strategies, including compatibility with Octopus time-of-use tariffs in the UK. The system can:

• Charge during off-peak, low-cost periods
• Discharge during high-rate peak periods
• Optimise charging behaviour based on forecast conditions

This allows users to maximise savings through strategic load shifting and improved self-consumption.

Emergency Power Supply (EPS)

The unit includes a dedicated EPS output for priority load management.

• <20ms switching time
• Pure sine wave output
• 4500W surge capability (30 seconds)
• 3600W rated backup output

Critical circuits such as refrigeration, communications, and lighting can remain operational during grid outages.

Designed to operate reliably alongside existing installations, it ensures efficient energy transfer, low harmonic distortion, and consistent output under varying load conditions.

• 230V rated AC voltage
• 50 / 60Hz frequency
• 16A rated AC output current
• 26A maximum AC input current
• 40A continuous AC passthrough
• Adjustable power factor (0.8 leading to 0.8 lagging)
• <3% THDi
