TSUN HEMS

About TSUN

TSUN (TSUNESS Co., Ltd., Suzhou, China, with a German office in Frankfurt) makes microinverters from 300 W single units to 3.3 kW 6-in-1 units. In Europe it is mainly found in 800 W balcony systems such as the TSOL-MS800, often combined with TSUN balcony storage (MSU2000, MSU4000Elite). Its monitoring app is TSUN Smart.

What is a Home Energy Management System?

A HEMS (Home Energy Management System) helps you get the most out of your solar installation. It monitors your PV production in real-time and automatically steers connected devices like EV chargers, heat pumps, and smart plugs to maximize self-consumption.

With Zerofy as your TSUN HEMS, you can:

• Monitor real-time solar production and home consumption
• Optimize self-consumption through intelligent device control
• Save on electricity bills with dynamic tariff integration
• Track your energy independence and CO₂ savings

Key Features

What TSUN offers on its own

Before connecting TSUN to Zerofy, it helps to know what TSUN offers on its own:

• EV charging: TSUN offers no EV charger and no surplus-charging function. An 800 W balcony system also stays below the about 1.4 kW a charger needs at its 6 A minimum.
• Heating: TSUN has no heat pump or heating-rod control in its product range.

How It Works

1. Connect your TSUN system – Zerofy connects to the TSUN cloud with your TSUN Smart login and reads your inverter data.
2. Add your devices – Connect your EV, charger, heat pump, or smart plugs
3. Enable Autopilot – Let Zerofy automatically optimize for solar self-consumption
4. Track your savings – Monitor your energy independence and cost savings

Good to know: Only TSUN Smart accounts work (inverter IDs starting with Y); TSUN Home accounts are not supported. Battery and meter data are only partly available, depending on the system.
