Description

This is not an inverter, but the box that decides what happens with the energy in the house. It is mounted between the grid connection and the home panel and, during a power outage, it takes over the supply of the entire house from the battery — not only of a few sockets chosen in advance, as happens with classic backup solutions. In addition, it includes an energy controller (EMMA) that coordinates the panels, the battery, the electric car and the heat pump, starting them or postponing them according to how much energy is available.

Switching is done in at most 20 milliseconds, that is less than a blink — the television, the computer and the boiler do not reset. It supports up to 63 A, as much as a single-phase house connection usually has, so a separate panel for the backup loads is no longer needed. If the main contactor fails, there is a manual by-pass that brings back the current from the grid. It consumes only 10 W for its own operation and measures energy with an accuracy of plus/minus 1%, which makes the reports in the app correct. It can coordinate up to 12 SG-Ready heat pumps, two charging stations for electric cars and 20 Shelly devices, starting them in the order of the established priority, according to how full the battery is. The IP55 enclosure is wall-mounted, and the noise stays below 29 dBA, that is practically imperceptible.

Rated AC voltage 220/230/240 V (L/N+PE); 63 A maximum current on the grid, on the backup output and on the non-backup one, 60 A on the connection towards the inverter. Maximum switching time 20 ms in Seamless mode and maximum 100 ms in protection mode; manual backup by-pass. It manages a SUN2000-2-6KTL-L1 or SUN2000-8-10K-LC0 inverter together with the LUNA2000 Smart String ESS batteries, up to two SCharger-7KS-S0 stations, 12 SG-Ready heat pumps and 20 Shelly devices, with prioritisation based on the battery SOC. Communication: 2 x RS485, LAN/WAN 10/100 Mbps, WLAN 802.11 b/g/n, 2 digital inputs and 2 digital outputs. IP55 enclosure, cooling by natural convection, below 29 dBA, 485 x 150 x 355 mm, maximum 14 kg.

Who it suits

Suitable for a single-phase home with a Huawei SUN2000 L1 or LC0 system and a LUNA2000 battery, which wants backup for the whole house and automatic coordination of the heat pump or of the electric car.

Terms explained

  • Whole home backup: Backup for the whole house: during a power outage the entire panel stays powered, not only a separate circuit of essential loads.
  • SOC: The state of charge of the battery, expressed as a percentage; the system uses it to decide which load starts first.
  • SG-Ready: A standard through which the heat pump accepts commands from outside, so as to work when you have solar energy in abundance.

Technical details

Specifications confirmed from the manufacturer's datasheet

Huawei SmartGuard-63A-S0 is not an inverter, but the single-phase backup box (whole home backup) of the FusionSolar ecosystem, with the EMMA energy controller integrated. It is mounted between the grid connection and the home panel and allows the entire house to be supplied on backup at up to 63 A, without an additional panel. The rated AC voltage is 220/230/240 V (L/N+PE), with 63 A maximum current on the grid, on the backup load output and on the non-backup one, respectively 60 A on the connection towards the inverter.

On a grid failure switching is done in a maximum of 20 ms in Seamless mode (maximum 100 ms in protection mode), so that sensitive loads do not reset. There is a manual backup by-pass for the situation of the main contactor failing. Its own self-consumption is 10 W, and the accuracy of the energy measurement is plus/minus 1%.

The integrated EMMA manages a SUN2000-2-6KTL-L1 or SUN2000-8-10K-LC0 inverter together with the LUNA2000 Smart String ESS batteries, up to two SCharger-7KS-S0 stations, 12 SG-Ready heat pumps and 20 Shelly devices, with prioritisation of the loads according to the battery SOC. Communication: 2 x RS485, LAN/WAN 10/100 Mbps, WLAN 802.11 b/g/n, 2 digital inputs and 2 digital outputs. IP55 enclosure, cooling by natural convection, below 29 dBA.
