The Tewaycell 30kWh All-in-One Solar Battery System is engineered to give you energy independence. It integrates a 51.2V 587Ah LiFePO4 battery, a 12kW 3‑Phase Hybrid Off‑Grid inverter, and an intelligent BMS with active cell balancing – all in a single, space-saving unit designed for home backup and daily energy savings.
Features:
✅ 30kWh All‑in‑One 3‑Phase ESS – This integrated system combines a 51.2V LiFePO4 battery, a 12kW 3‑phase hybrid inverter in a single, space‑saving cabinet.
✅ Grade A+ LiFePO₄ Battery with 10,000+ Cycles – Powered by premium HITHIUM 587Ah cells, designed for long‑term home energy storage.
✅ Built‑in Active Balancer – Actively stabilizes cell voltage, minimizes voltage drift, and extends the overall lifespan of the battery pack for consistent, reliable performance.
✅ Intelligent Multi‑Source Charging – Supports PV solar charging, grid charging, or simultaneous charging from both sources for maximum flexibility.
Note: Grid charging is supported, but the system does not feed power back to the utility grid.
✅ Peak Shaving & Valley Filling – Time‑of‑use scheduling enables users to charge during off‑peak low‑tariff hours and discharge during peak high‑tariff hours, maximizing electricity cost savings.
✅ Multi‑Layer Safety with Built‑in Aerosol Fire Suppression – Automatically triggered by heat, the built‑in fire protection system enhances indoor safety and gives you peace of mind.
✅ Bluetooth & Wi‑Fi Remote Monitoring – Smart 300A BMS with optional Wi‑Fi module enables easy remote monitoring and control via smartphone from anywhere.

Frequently Asked Questions
Q: What solar power can this all‑in‑one system 30kWh lifepo4 lithium battery support?
A: Dual MPPT, each tracker max 9000W, total PV input up to 18kW.
Q: Is this all‑in‑one 51.2V 587Ah 30kWh lifepo4 batterie suitable for indoor installation?
A: Yes, designed for indoor installation. Please keep good ventilation environment, do not install outdoors.
Q: Does this unit support peak‑valley load shifting? Can it charge from mains electricity?
A: Yes. This 12kW hybrid inverter energy storage system supports time‑slot charge/discharge and allows charging from utility grid for peak‑valley load shifting.
Q: Can I expand power and capacity by parallel connection?
A: It is 51.2V 12kW 30kWh expandable all‑in‑one solar inverter system and there are 2 expansion ways for this all‑in‑one ESS:
1. Full unit parallel (increase total output power & capacity): Maximum 6 identical all‑in‑one units can be paralleled together to boost the whole‑system AC output power and energy storage capacity. Only the same model is allowed for full‑unit parallel.
2. Battery‑port capacity expansion (only expand storage capacity): On the battery port of one single unit, you can connect up to 15 identical battery packs such as MB51587-300A-HWB in parallel for higher energy capacity.
