Stackable 10kW 30kWh All In One Energy Storage System with 15kW PV

Modular Solar Storage Without a Fixed Cabinet Configuration

This stackable 10kW 30kWh all in one energy storage system combines a pure sine wave inverter, two battery modules, dual MPPT solar charging, priority-load outputs and energy monitoring in one coordinated platform.

The battery section provides 30.72kWh of rated energy and approximately 27.6kWh of usable energy at 90% depth of discharge. Its modular construction allows the inverter and battery sections to be transported, positioned and installed as separate stackable components.

With up to 15kW of photovoltaic input under the dual MPPT configuration, the system is designed for larger residential solar projects, villas, home offices and properties requiring extended battery reserve with a 10kW output platform.

Why Choose a Stackable 10kW 30kWh Energy Storage System

15kW PV Input for Faster Battery Recovery

The solar charger supports either a single-MPPT or dual-MPPT configuration. When one MPPT is used, the system supports up to 27A and 9kW of photovoltaic input. When both MPPT channels are used, total photovoltaic input can reach 22.5A and 15kW.

A larger solar array can improve energy collection outside peak sunlight hours while also supplying compatible daytime loads. The final array must remain within the approved operating-voltage, current and open-circuit-voltage limits.

• Use separate MPPT channels for suitable roof sections or string arrangements.
• Keep the photovoltaic operating voltage within 60–450Vdc.
• Keep total open-circuit voltage below 500Vdc.
• Calculate string voltage using the lowest expected site temperature.
• Confirm cable size, connectors, polarity and DC protection before commissioning.

Dual AC Output and Generator-Assisted Backup

Dual AC output allows installers to separate essential circuits from lower-priority loads. This helps preserve battery energy during outages and provides clearer control over which appliances remain active.

Lighting, refrigeration, communication equipment, security systems and home-office devices can be assigned to the priority load group. Selected outlets and compatible nonessential appliances can be assigned to the secondary output.

Generator support provides an additional charging or supply option during prolonged outages or periods of limited solar production. Generator voltage, frequency and available output power must match the system requirements.

Electrical and Installation Specifications

Stackable 10kW 30kWh ESS FAQ

How is the 30kWh battery capacity arranged?

The battery section consists of two 15.36kWh modules, providing 30.72kWh of rated energy and approximately 27.6kWh of usable energy at 90% depth of discharge.

Why use a stackable design instead of one large cabinet?

Separate inverter and battery modules reduce the weight of each component during transport and site handling. They also provide more flexibility when moving equipment through narrow access areas.

Can the system use a 15kW solar array?

Yes. The dual MPPT configuration supports up to 15kW of photovoltaic input, provided the current, operating-voltage and open-circuit-voltage limits are followed.

How should the two AC outputs be used?

One output can serve priority circuits while the second manages flexible loads. The final arrangement depends on the selected operating mode and electrical distribution design.

Can a generator charge the battery during a long outage?

Generator operation is supported. The generator must provide compatible voltage, frequency and sufficient power for the planned battery-charging and load requirements.

What installation space should be prepared?

The site should provide stable support for the stacked modules, dry protected placement, suitable ventilation, cable access and sufficient clearance for commissioning and maintenance.
