Integration

Compatibility with leading inverters

Our systems are field-integrated with leading hybrid inverters (Deye, Solax, GoodWe, Sungrow, Growatt, Fox ESS, Solis). On request, we confirm the compatibility of your specific inverter (CAN/RS485 and the required parameters) and send connection instructions.

How we work

A 4-step process

From the initial enquiry to system commissioning — clear pricing and protocols at every stage.

1

Enquiry

You share your needs: capacity, power, location and timeline.

2

Configuration

We propose the exact model and options with clear pricing and a deposit.

3

Design and testing

We build and test the system with protocols — lead time depends on the configuration.

4

Delivery & commissioning

We deliver, a regional partner installs, and we commission and configure the system.

Questions

Frequently asked questions

Rule of thumb: daily consumption × days of autonomy ÷ usable DoD.

Example: 18 kWh/day × 0.5 days ÷ 90% ⇒ ≈ 10 kWh.

If you have PV or plan to expand, go one step up. Fastest way: the configurator shows a price instantly, and on request we calculate 2–3 options based on your consumption, PV and inverter — free of charge.

Yes — our systems are field-integrated with the leading hybrid inverters (Deye, Solax, GoodWe, Sungrow, Growatt, Fox ESS, Solis) over CAN/RS485 with correct data exchange (SoC, current, voltage, alarms).

On request we confirm your specific model and send wiring instructions. If you don’t have an inverter yet, we’ll recommend a suitable one.

We use new automotive-grade Li-ion NMC cells (CATL/BYD) and our own BMS with active balancing, temperature and insulation monitoring.

We provide a 7-year warranty with manufacturing and service in Europe, and the system is designed for daily cycling well beyond that period. Via ENEKTRI Cloud we monitor its health 24/7 and fix issues remotely (OTA) — often before you notice them.

Yes — protection works on several levels: BMS with overcharge and deep-discharge protection, temperature control and insulation monitoring, design and testing to IEC 62619, climate control and an optional fire-suppression system.

Installation is carried out by a trained partner in your region; commissioning and configuration — by our engineers.

You see the exact price instantly in the configurator — it depends on capacity and power.

  • Daytime PV energy keeps working in the evening and at night.
  • Charge on cheap night tariffs, use during peak hours.
  • Backup — your home keeps running during outages.

Every system includes a free 1-year ENEKTRI Cloud licence.
