Solutions
Is your solar installation fighting you? Here is how TED fixes it.
Each page starts from a real problem faced by solar battery owners, explains why the usual approaches fall short and shows how TED solves it, locally, from Home Assistant.
Make several battery and inverter brands work together
Each manufacturer app ignores other brands. TED makes them work together under one setpoint.
Read the solutionGo beyond the limits of your manufacturer's HEMS
One brand, few settings, a limited number of devices: TED goes beyond these limits, with or without the original HEMS.
Read the solutionMultiple batteries oscillating or passing energy back and forth
Each battery corrects the meter on its own and fights the other. TED computes one setpoint for all of them.
Read the solutionZero export and maximum self-consumption with batteries
Surplus exported at noon, imports in the evening: TED keeps the grid close to 0 W, continuously.
Read the solutionCharge your batteries from the grid during off-peak hours
Little sun in winter: TED recharges your batteries off-peak so you can use them at peak times.
Read the solutionUse your solar surplus: water heater, smart plugs, scripts
Batteries full, surplus exported: TED switches on your water heater, plugs or Home Assistant scripts following your rules.
Read the solutionProtect your solar batteries: thresholds, power limits, faulty devices
Thresholds, maximum power, faulty devices excluded then retested: each battery stays within its limits.
Read the solutionControl several Zendure units (SolarFlow, Hyper) in Home Assistant
Several SolarFlow and Hyper units, with or without the Zendure app: the brand TED has tested and validated.
Read the solutionA local HEMS for Home Assistant, with no YAML to write
No more dozens of automations: a local, ready-to-use HEMS configured from a web interface.
Read the solutionTED compared with the usual approaches
What TED brings compared with a manufacturer app or hand-written Home Assistant automations.
| Manufacturer HEMS | DIY automations | TED | |
|---|---|---|---|
| Several brands in a single control loop | No | Partial | Yes |
| Number of inverters and batteries | Limited by the app | Unlimited, but you write everything | Unlimited |
| One setpoint shared across all batteries | Its own brand only | Partial | Yes |
| Keep the manufacturer HEMS and add other batteries | No | Partial | Yes |
| Battery thresholds and max power per device | Partial | Partial | Yes |
| Faulty device excluded then retested automatically | No | No | Yes |
| Scheduled charging during off-peak hours | Partial | Partial | Yes |
| Loads switched on surplus (AND / OR rules) | No | Yes | Yes |
| Works without the manufacturer cloud | Depends on the brand | Yes | Yes |
| Ready-made interface, no YAML | Yes | No | Yes |
General comparison: what manufacturer HEMS can do varies between brands and models.
