Key Features

Why Choose the 12kW / 30kWh Home ESS?

A high-capacity residential energy storage system featuring dual 6kW inverters in parallel and an expandable 30kWh LFP battery stack — engineered for large homes, high-consumption households, and whole-home backup power.

Dual Inverter

2 × 6kW Parallel Inverter Architecture

Two 6kW hybrid inverters operate in parallel via a DC convergence box, delivering a combined 12kW of continuous AC output. The modular dual-inverter design provides built-in redundancy — if one unit requires maintenance, the other continues supplying power. Each inverter features independent MPPT solar charging, enabling flexible PV array configuration and maximising generation across different roof orientations.

30kWh Expandable

30kWh Expandable LFP Battery Stack

Three battery modules connect in parallel via CAN and RS485 bus, delivering 30kWh of usable energy — enough to power a large home for 24+ hours or sustain critical loads through extended grid outages. Each module has an independent BMS with address configuration (ADDR) and SOC display. The stack is field-expandable: additional modules can be added without replacing existing hardware, protecting your investment as energy needs grow.

CAN / RS485 BMS

Multi-Module BMS with CAN & RS485 Communication

Each battery module communicates with the inverter via dual-protocol CAN and RS485 bus, enabling real-time cell-level monitoring, SOC balancing across all modules, and coordinated charge/discharge management. The RESET and ADDR functions allow individual module identification and fault isolation without shutting down the entire system — minimising downtime and simplifying maintenance in multi-module configurations.

Whole-Home Backup

Whole-Home Backup & Solar Self-Consumption

With 12kW of inverter power and 30kWh of storage, the system can back up an entire large home — including air conditioning, EV charging, and high-draw appliances — during grid outages. In normal operation, the integrated EMS maximises solar self-consumption, charges the battery from surplus PV generation, and dispatches stored energy during peak tariff periods, delivering electricity bill savings of up to 90% for high-consumption households.
