What is the Huawei SUN2000-5-12K-MAP0, and what makes it stand out?
- A three-phase inverter family in 5 sizes: 5 / 6 / 8 / 10 / 12 kW — pick the one that fits how your home or villa actually uses power
- Up to 98.4-98.6% efficiency: converts panel power into household power with very little loss
- Battery-ready: supports Huawei LUNA2000 (S0/S1) and whole-home backup with SmartGuard, switching over in ≤ 20 ms
- Active safety: AFCI arc-fault shutdown, RSD (with optimizers) and temperature sensing on the PV and battery terminals
- Weatherproof: IP66 for outdoor mounting, ≤ 29 dB noise, no fan
The inverter is the heart of any solar system, and the Huawei SUN2000-5/6/8/10/12K-MAP0 is the range we use for homes and villas on three-phase power. This page condenses the key specs from Huawei's official datasheet (version 02-202406) into one easy read — output power, efficiency, the battery system, safety features and operating conditions — with a link to download the original file at the end.
What is the SUN2000-5-12K-MAP0
Huawei calls this model a "Smart Energy Controller" because it does more than an ordinary inverter — besides converting DC from the panels into three-phase AC for the house, it works as an energy hub that connects directly to LUNA2000 batteries, delivers whole-home backup together with the SmartGuard unit, and reports to the FusionSolar app over built-in WLAN.
The family comes in five sizes by rated output: 5, 6, 8, 10 and 12 kilowatts — covering everything from a mid-size home to large villas with heavy usage (see our Thai-language guide on how to size a solar system)
Datasheet highlights
- High efficiency: max efficiency of 98.4% (5K model) up to 98.6% (6K-12K models), with a European weighted efficiency of 97.5-98.2%
- 2 MPPTs: tunes two independent panel groups — for example roof faces pointing different ways — with up to 16 A per MPPT and a recommended max PV power of 9,000-22,000 Wp depending on model size
- Active safety: AFCI arc-fault detection and shutdown, panel-level rapid shutdown RSD (when installed with optimizers) and temperature sensors on both the PV and battery terminals
- Full protection set: DC reverse polarity protection, insulation monitoring, DC/AC Type II surge protection (EN/IEC 61643-11), residual current monitoring, AC overcurrent/short-circuit/overvoltage protection and anti-islanding
- 100% unbalanced three-phase load support: a phase working harder than the others still gets full output, plus an off-grid mode that handles momentary overloads of up to 200% for 10 seconds
- Ready to grow into a battery system: connects to LUNA2000 S0/S1 series batteries out of the box, charges at up to 12,000 W, and supports battery charging from the grid
- Quiet and durable: natural convection cooling with no fan, noise ≤ 29 dB, IP66 rated, night-time consumption below 5.5 W
- Grid-connection standards: certified against requirements in many countries, including Thailand's MEA/PEA (see the Thai-language guide to the PEA permit process)

Who it's for
- Homes and villas on three-phase power: this is a purpose-built three-phase inverter — right for large homes, villas and pool villas running multiple air conditioners, water pumps, pool pumps or an EV charger (if your home is on single-phase power, we'll recommend the right model during the free site survey)
- Systems in the 5-12 kW range: covers the most popular residential system sizes — pick by your actual usage, with PV oversizing headroom per the recommended values in the table
- Anyone planning battery storage: install batteries on day one or add them years later — LUNA2000 support is built in, no inverter swap needed (read more: hybrid solar with battery backup in Phuket)
- Areas with brownouts or frequent outages: paired with batteries and the SmartGuard-63A-T0, you get whole-home backup that switches over in no more than 20 milliseconds
