What TedEnergy does for you

A HEMS that works for your installation, not for a brand.

Six reasons to replace, or complement, your manufacturer's HEMS.

Every brand, one regulation

Mix Zendure, Marstek, Huawei, Victron… TedEnergy shares a single setpoint according to the level and power of each battery, with no software limit on the number of inverters.

In detail

Each inverter is "controlled" (the software drives its charge and discharge) or "monitored" (its production and level are taken into account without driving it). Inverters can be grouped into clusters and zones. Assisted mode keeps the manufacturer's HEMS in place and adds your other inverters as reinforcement. Different brands and capacities: the split follows each battery's level.

The meter as close to zero as possible

With every new meter reading, about every two seconds, the setpoint is recalculated and shared out. Surplus goes into the batteries; the house draws from them at the right time.

In detail

Adjustable Autonomous mode target (zero export, zero import or a range), per season or date range. The regulation accounts for setpoints sent but not yet applied, learns each battery's real power, wakes a standby inverter progressively and spots an inverter that does not apply its setpoint (error 01) to set it aside then retest it. Single-phase or three-phase grid, regulation on the sum or phase by phase.

100% free-form automations

Water heater, heat pump, electric car, pool: you decide when and how, without writing a line of code.

  • Don't drain the batteries into the car
  • Heat water with the solar surplus
  • Full charge every Sunday
  • Limit charging above 40 °C
In detail

Nested AND / OR conditions on any value: production, a battery's level or temperature, an appliance's power, time, date, Tempo day, Home Assistant entity, Zendure cloud value. Actions: switch a device on or off, call a Home Assistant service or a webhook, impose a minimum or maximum level on the batteries, limit or disable an inverter, change a setting, send a notification. Ready-made templates: off-peak hours, red Tempo day, car charging, night reserve, calibration, surplus to an appliance…

Peak shaving: keep for instance 30% in reserve in the batteries and only use it when the house exceeds your contracted power. The breaker no longer trips, and you can sometimes lower your contract.

A lower bill

Off-peak hours, Tempo, super off-peak hours: the batteries charge at the right time, and the summary shows what you save, in euros, day after day.

In detail

Your contract's tariff grid (base, peak / off-peak, Tempo, Zen, custom grid) fetched automatically or drawn by hand. Scheduled charging during off-peak hours, daily summary per period in kWh and euros, surplus resale, daily, weekly or monthly PDF reports. Charging powers are capped by your contract so the breaker never trips.

Batteries that last

Optimised charging keeps two inverters ready and leaves the others on standby: 18.7× fewer charge / discharge reversals and 28% less running time than a simple split, on a real October day.

In detail

Minimum and maximum levels per battery, charge restart margin, monitored calibration, an alert when the voltage gap between a battery's cells becomes abnormal, maximum powers per inverter. An inverter that starts and stops less often puts less strain on its relays, its electronics and its battery management system.

Your installation in your pocket

The free Android app shows your home live and lets you act on your inverters, at home or remotely.

In detail

Signed remote access, without a VPN or extra account; notifications from your rules; enable, disable, unlock an inverter; today's summary. The configuration stays in the web interface, on your network.

No lock-in

Connect your devices the way you like.

An always-on server is enough: a NAS, a mini-PC, a Raspberry Pi or Home Assistant OS. The software then talks to your inverters directly.

Solutions

Which problem do you want to solve?

The situations solar battery owners run into most often, and the answer to each one.

Make several battery and inverter brands work together

Each manufacturer app ignores other brands. Here, they all work together under one setpoint.

Read the solution

Virtual battery: control several batteries as one

One setpoint for all your batteries: they share the work instead of getting in each other's way.

Read the solution

Go beyond the limits of your manufacturer's HEMS

One brand, few settings, a limited number of devices: go beyond these limits, with or without the original HEMS.

Read the solution

Multiple batteries oscillating or passing energy back and forth

Each battery corrects the meter on its own and fights the other. One setpoint, computed for all of them, ends the ping-pong.

Read the solution

Zero export and maximum self-consumption with batteries

Surplus exported at noon, imports in the evening: keep the grid close to 0 W, continuously.

Read the solution

Charge your batteries from the grid during off-peak hours

Little sun in winter: recharge your batteries off-peak and use them at peak times.

Frequently asked questions

Before you start

What exactly is TedEnergy?

TedEnergy is a multi-brand HEMS (home energy management system) that runs at home, on your own server (NAS, mini-PC, Raspberry Pi) or in Home Assistant OS. It reads your meter about every two seconds, then adjusts charging and discharging of all your inverters and batteries so they work together, like one big battery. It connects to your devices through the manufacturer's cloud (Zendure), its built-in MQTT server or Home Assistant.

Do I need Home Assistant?

No. With a Zendure inverter (through the local API, the Zendure cloud or local MQTT) and a meter read directly (Shelly, or any MQTT meter such as the Zendure Smart Meter 3CT), TedEnergy works on its own on any Docker server. Home Assistant is still recommended for other brands, and it is the simplest installation (Home Assistant OS guide).

Is my Zendure Hyper 2000 compatible?

Yes. Every Zendure inverter linked to the Zendure app is controlled through the Zendure cloud, including the Hyper 2000, the SolarFlow Hub 1200 / 2000, the AIO 2400 and the ACE 1500, which have no local communication. Every Zendure model is used and validated by our users. One connection per Zendure account: TedEnergy or Home Assistant's Zendure integration (TedEnergy then republishes its values to Home Assistant).

How many inverters can I control?

The software sets no limit: our reference installation regulates about ten. The license offered at installation lets you control everything for 30 days; after that, the number of controlled inverters depends on your license (see the Support page). Monitored inverters are never limited. The other limit is your electrical installation, which you frame with the maximum charge and discharge powers.

Does TedEnergy wear out my batteries?

Quite the opposite: on a real day, optimised charging makes almost nine times fewer charge / discharge reversals than a simple split, with a third less running time (a real day, minute by minute). Each battery's minimum and maximum levels are respected, calibration is monitored and an abnormal voltage gap between a battery's cells triggers an alert.

Where does TedEnergy run?

On an always-on machine. Home Assistant OS: an app added in a few clicks (Home Assistant OS guide). Synology NAS: entirely with the mouse in Container Manager (Synology guide). Docker: one command on a mini-PC, a Raspberry Pi or a Linux server (public image tedenergy/ted on Docker Hub). To discover it without installing anything, open the show home. Everything is explained in the installation guide.

How much does TedEnergy cost?

Nothing, until further notice. At installation, a license is offered so you can use every feature for 30 days. You can support the project through the fundraiser: some rewards come with a license with extended rights, for the duration shown on the fundraiser. Details on the Support page.
