Frequently Asked Questions
Q: Can I mix 28kWh and 32kWh units when paralleling this 3‑phase energy storage system?
A: Not recommended. Please parallel units with identical capacity only. Mixed‑capacity parallel will cause imbalance and accelerate LiFePO4 battery aging.
Q: What solar power can this all‑in‑one ess support?
A: Dual MPPT, each tracker max 9000W, total PV input up to 18kW.
Q: Is this 51.2V energy storage unit 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：Yes, 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 TW-MB51628-300A-HWB in parallel for higher energy capacity.
