IP65 per the IEC 60529 standard. The first digit 6 = Dust-tight (100% dust-proof). The second digit 5 = 6.3mm water jets from any direction, withstanding a garden hose and driving rain. Suitable for installation under an open roof, on a balcony, or in a carport. QES Battery is one of the few models on the market that can be installed outdoors.

What size home is it suited for?

16.08 kWh is enough for a typical residential home for 1-2 days, with max power of 7,680W per unit. Large households or homes with EV charging should look at 3-5 units in parallel (48-80 kWh).

Why choose LiFePO4 instead of NMC?

LiFePO4 is safer than NMC, far less prone to fire with thermal runaway around 270°C, long life at 8,500 cycles vs NMC's 2,000-3,000 cycles, and cobalt-free. Ideal for Thailand's hot climate.

How does the BMS manage 15 units in parallel?

Each unit has an independent BMS handling cell balancing, temperature, and current limits. Units are linked via CAN 2.0 daisy-chain, the Master BMS aggregates the pack and reports to the inverter. Faulty units are isolated automatically. Monitor status via the WiFi/Bluetooth app.

// THE KEY FEATURE

IP65 · Born for Thailand

QES Battery is among the first home LiFePO4 batteries to achieve IP65 — fully dust-tight + resistant to water jets from any direction · install outdoors / in a carport / on a balcony / in rain-exposed areas right out of the box

IP65

// IEC 60529 · PROTECTION CLASS

What is IP65, really?

IP6X — Dust-tight (100% dust-proof) suited for warehouses and construction sites

IPX5 — withstands 6.3mm water jets from any direction (equivalent to driving rain or a garden hose) suited for heavy rain and typhoons

Most batteries in the market are only IP55 or lower — cannot install outdoors

Heavy Rain / Storm

Withstands water jets from any direction — unfazed by sideways rain or splash from the roof

Install Outdoors

Mount in a carport, on a balcony, or under an open roof — save indoor floor space

Insect + Dust Proof

100% dust-tight — protects against small insects, construction dust, and windblown sand

Flood Resistant

Tall 1007mm form factor + wheels at the base — easy to lift above floodwater, never sitting flat on the floor

Frequently Asked Questions

Yes — QES Battery is QES Energy's own brand · manufactured by GSL (a vertically integrated LiFePO4 manufacturer — exporting to 138+ countries · 100,000+ customers) · uses Grade A1 cells · model-specific BMS · QES handles warranty claims, commissioning, and after-sales support directly · contact Line @qesenergy

IP65 per the IEC 60529 standard — the first digit 6 = Dust-tight (100% dust-proof) · the second digit 5 = 6.3mm water jets from any direction (withstands a garden hose or driving rain) · suitable for installation under an open roof, on a balcony, or in a carport — but do not submerge it or expose it directly to harsh sunlight · avoid flood zones where water can rise above 50cm · QES Battery is therefore one of the few models on the market that can be installed outdoors

It depends on your load — 16.08 kWh ≈ 1-2 days for a typical home (averaging 8-10 kWh/day) · note the max power of 7,680W per unit — if running several air conditioners simultaneously, you may need 2 units in parallel · large households or homes with EV charging should look at 3-5 units (48-80 kWh)

QES Battery uses the standard Pylontech/BYD protocol over CAN 2.0 / RS485 — supporting virtually every LV Hybrid inverter: GoodWe ES/EM/EH, Solis S6-EH, Deye SUN-LV, Growatt SPH/SPF, Sungrow SH-RS, SRNE, Voltronic Axpert/Infini, Victron MultiPlus-II, Felicity, EASUN, SOK · we verify compatibility before you order

LiFePO4 (Lithium Iron Phosphate) is clearly safer than NMC — (1) far less prone to fire · thermal runaway around ~270°C (NMC = 150°C) · (2) long life at 8,500+ cycles vs only 2,000-3,000 cycles for NMC · (3) cobalt-free (lower cost + ethical sourcing) · QES Battery uses LiFePO4 throughout — ideal for Thailand's hot climate

Each unit has an independent BMS handling its own cell balancing, temperature, and current limits · units are linked via CAN 2.0 daisy-chain · the Master BMS aggregates the entire pack and reports to the inverter · if a unit has a fault, the system isolates it automatically without affecting the others · monitor each unit's status via the WiFi/Bluetooth app
