Sinexcel iSUNA 10000T-20000T

More power, more flexibility, more places.

- Max. PV input current – 18 A (10-40 % higher than Gowatt, Deye, Megarevo, Solis, GoodWe, GivEnergy, Aiswei)

- MPPT voltage window – 80 V – 550 V, wakes up at only 95 V → grabs dawn & winter sun earlier

- Peak efficiency – 98 %, beats every rival on the sheet by 0.4-1.8 %

- Parallel expansion – up to 6 units (18 → 36 kW); Megarevo & Gowatt stop at 4

- Weight – just 21 kg, ~10 kg lighter than most → one-person install, lower freight cost

- Noise – < 25 dB(A), 5-10 dB quieter → virtually silent on terraces or in indoor garages

- Altitude rating – full power to 5 000 m, double or triple most brands (2 000-4 000 m)

- Humidity & dust – IP 65, 0-100 % RH → outdoor-ready in tropics or desert

- Natural cooling – fan-less → no dust, no maintenance, longer lifetime

- Battery freedom – Li-ion or lead-acid, dual independent battery ports ready

12 kW Low-Voltage Model – Key Wins vs. Deye SUN-12K-SG04LP3-EU

• Higher European efficiency – 97.7 % vs. 97 %: every ray is money.

• Peak efficiency – 98.2 % vs. 97.6 %: industry-top conversion, lower heat, longer life.

• Wider battery window – 33–60 V vs. 40–60 V: accepts more battery brands, old or new.

• Two independent battery ports vs. one: mix new & used packs, expand later without wasting the first investment.

• DC over-sizing – 18 kW PV vs. 15.6 kW: 1.5× head-room boosts winter and morning yield.

• Three MPPTs (20 A each) vs. two: east-west-roof, complex shading – full harvest.

• Higher string current – 20 A on all MPPTs vs. 26 A/13 A split: ready for 550 W+ modules.

• Broader PV voltage – 160–960 V vs. 200–650 V: longer strings, fewer combiner boxes.

• Stronger output – 14.4 kW vs. 13.2 kW: powers more loads and sells more to the grid.

• Higher AC throughput – 36.4 A grid input / 22 A output vs. 20 A/19.1 A: faster charging, firmer backup.

• Built-in generator port – automatic start/stop for off-grid sites; rival needs extras.

• Isolated topology – transformer inside for safer grounding and wider battery choice.

• Slim & silent – 460 × 650 × 165 mm, <45 dB: fits utility rooms, balconies, apartments.

• Rich connectivity – Wi-Fi, 4G, Bluetooth, RS485: commission and monitor even without internet.

• APP-based setup – no screwdriver menus, finish commissioning in 3 minutes.

15 kW High-Voltage Model – Key Wins vs. Deye SUN-15K-SG01HP3-EU-AM2

• European efficiency – 97.7 % vs. 97 %: more kWh per kW installed.

• Peak efficiency – 98.2 % vs. 97.6 % thanks to full-SiC power stage, design life ≥20 years.

• Dual battery ports (100 % independent) vs. single: run two different brands, chemistries or ages; if one pack fails the other keeps the lights on.

• Wider HV battery range – 125–800 V vs. 160–700 V: welcomes tomorrow’s higher-voltage sodium or LFP packs.

• Two MPPTs, 2×2 strings, 4 strings total vs. 2×1: mount on multiple roof facets without power clipping.

• Altitude champion – full operation to 5 000 m (derate >3 000 m) vs. 2 000 m: reliable in the Andes, Alps, Himalayas.

• Bigger parallel fleet – up to 15 units (225 kW) vs. 10: scale a single site without extra hardware.

• Whisper quiet – <45 dB vs. <55 dB: neighbour-friendly on terraces or carports.

• Chemistry freedom – lithium, sodium, lead-acid: no firmware lock-in, future-proof your storage.
