Split Phase All In One Energy Storage System 10kW 30kWh Home Solar Power Battery

Split Phase 10kW 30kWh All In One Energy Storage System for Home Backup

High-Capacity Split Phase Solar Storage

This 10kW 30kWh all in one energy storage system combines split phase inverter output, battery storage, dual MPPT solar charging, generator compatibility and remote monitoring within one integrated cabinet.

The battery provides 30.72kWh of rated energy and approximately 27.6kWh of usable energy at 90% depth of discharge. It is designed for larger residential properties, villas, remote homes and projects requiring longer backup duration than standard home battery systems.

Its 120/240Vac split phase architecture is suitable for electrical systems using L1, L2 and neutral connections. The 10kW pure sine wave output can support multiple compatible household circuits after continuous and startup loads have been properly assessed.

Why Choose This All In One Energy Storage System

Dual AC Output for Priority Load Management

The dual AC output design helps installers separate priority backup circuits from lower-priority household loads. This supports clearer energy management when battery capacity or available solar generation is limited.

Priority Household Circuits

Lighting, routers, refrigerators, communication equipment, security systems and home-office devices can be prioritized according to the project requirements.

Higher-Power Residential Loads

Selected pumps, air conditioners and other motor-driven equipment may be considered after their continuous power and startup demand have been checked against the inverter limits.

Generator-Supported Applications

A compatible generator can provide an additional charging or supply source for remote homes and locations with extended utility outages. Generator voltage, frequency and wiring must match the system requirements.

Electrical and Charging Specifications

Solar and Site Planning

The dual MPPT solar charger supports two photovoltaic inputs rated at up to 22A and 5kW each. Both solar strings must remain within the 90–485Vdc operating range and below the 500Vdc open-circuit voltage limit.

• Calculate solar string voltage at the lowest expected site temperature.
• Keep each photovoltaic input within its 22A current limit.
• Confirm DC cable size, polarity, connectors and protection devices.
• Provide stable floor support suitable for the 255kg cabinet weight.
• Install the IP21 cabinet in a dry indoor or protected technical location.
• Apply output derating when the installation altitude exceeds 1000m.

All In One Energy Storage System FAQ

What type of electrical system does this unit support?

It is designed for 120/240Vac split phase electrical systems using L1, L2 and neutral connections.

How much battery energy is available?

The system provides approximately 27.6kWh of usable battery energy when operated at 90% depth of discharge.

Why does the system have dual AC outputs?

Dual outputs allow installers to organize household loads according to priority and the selected system operating strategy.

Can a generator be connected?

Generator operation is supported. The generator output voltage, frequency, power capacity and wiring must be confirmed before commissioning.

Can the cabinet be installed outdoors?

The enclosure is rated IP21 and should be installed in a dry indoor or protected technical area. It is not presented as a weatherproof outdoor system.

What information is needed for a quotation?

Provide the installation country, split phase voltage, continuous and startup loads, required backup duration, solar module data, generator specifications, installation environment and order quantity.
