Charging from solarwith any inverter
The e:car WALL SMART wallbox has its own meter on the main supply. It detects how much electricity is being exported to the grid and charges the car from rooftop surplus. It does not talk to the inverter, so the inverter brand doesn’t matter.
Measures itself, no inverter needed
Meter on the main supply
SMART sees the house consumption and the export to the grid and adjusts the charging power smoothly.
Works with any solar system
The brand and age of the inverter don’t matter – even after replacing the PV system or with two inverters.
Three charging modes
Normal protects the main breaker, Eco charges from surplus only, Boost charges at full power when you’re in a hurry. You switch them in the app.
Smart home control
Via Modbus TCP you can connect the station to Home Assistant, Loxone or a building energy management system.
Home Assistant →Only SMART charges from surplus
Any wallbox uses electricity from your own plant while the sun is shining. Controlling charging according to the export, however, needs a model with a meter.
| BASIC | SMART | |
|---|---|---|
| Charging from surplus (Eco mode) | no | yes |
| Main breaker protection | no, fixed power | dynamic |
| Own meter on the main supply | no | yes, included |
| Consumption metering and app | no | yes |
| Modbus TCP and Home Assistant | no | yes |
| Price from (excl. VAT) | CZK 14,900 | CZK 21,900 |
Why combine a wallbox with solar
Cheaper kilometres
Rooftop electricity you would otherwise sell to the grid at the feed-in price powers your car.
Higher self-consumption
A car is a big battery on wheels – it absorbs surplus the house can’t use.
No overloaded breaker
SMART watches the main breaker and adapts the station’s power to the house consumption.
Subsidy for family houses
Households can get CZK 10,000 per charging point as part of the solar PV subsidy (the Oprav dům po babičce programme; PV only together with insulation).
Carport and solar fence
Wallbox under a solar carport
A carport with solar panels protects the car from the weather and generates electricity right above the parking space. The wallbox can be mounted directly on a carport column.
Charging via a solar fence
Instead of standard fence panels you can fit solar panels and mount the wallbox directly on the fence. The space by the driveway then generates electricity and serves for charging.
The wallbox is installed by a certified IONT partner.
Frequently asked questions
Does the SMART wallbox work with my inverter?
Yes, with an inverter of any brand. SMART does not communicate with the inverter – it measures the export with its own meter on the main supply of the house. It therefore keeps working after replacing the PV system or with several inverters.
Can the BASIC model charge from surplus?
No. BASIC charges at a fixed power and has no meter. It uses solar electricity only if the panels happen to be producing; charging controlled by the export is only possible with SMART in Eco mode.
How do I connect the wallbox to Home Assistant?
Via Modbus TCP on the local network. You can then control the station from Home Assistant, Loxone or a building energy management system; the control logic runs on your premises, not in the cloud.
Is there a subsidy for a wallbox with solar PV?
Households can get CZK 10,000 per charging point as part of the solar PV subsidy in the Oprav dům po babičce programme (PV only together with insulation).
What if I charge in the evening when the panels aren’t producing?
Switch to Normal mode in the app – the station then charges from the grid and makes sure the main breaker of the house is not overloaded.

Have a solar PV system?
The inverter brand doesn’t matter. We will prepare a quote for a SMART wallbox including the meter; installation is carried out by a certified IONT partner.
