Inverter / voltage converter selection

Recommended inverter: 3000 W (Continuous: 2647 W, Peak: 4235 W)

Inverter operating mode

Inductive loads (2× surge): Indukční deska

Inverter idle self-consumption

40 W × 4 h/day = 160 Wh/day

Inverter no-load self-consumption (idle consumption)

Load concurrency matrix (simultaneity factor)

Concurrency OK

Concurrency factor 1 · connected 1800 W / inverter 3000 W

Sum of 230 V appliances is within continuous inverter power — unrestricted concurrent use.

Pay-per-export

Premium engineering audits included in the PDF

Available in the installation blueprint

DC-DC alternator charging & idle overload protection

Full input/output sizing for voltage conversion (e.g. 12V alternator → 24V traction). Safe D+ sense wiring for Euro 6 smart alternators and idle overload protection.

Available in the installation blueprint

230 V shock protection & N-PE bonding (IEC 60364)

Inverter grounding-relay wiring and chassis ground placed after the shunt so the RCD/RCBO works without floating chassis voltage.

Available in the installation blueprint

Enclosure thermal audit & ventilation m³/h

Dynamic heat-loss sum from inverter, MPPT and DC-DC at full load (estimate: 317 W). Exact ventilation airflow in m³/h to protect cells from degradation.

Available in the installation blueprint

Global & seasonal solar analysis (4 seasons by world destination)

Detailed energy production matrix (Spring, Summer, Autumn, Winter) for the selected world destination, including southern-hemisphere calendar alignment. Battery sizing for overcast days and DC-DC booster drive-time to bridge the deficit.

Available in the installation blueprint

Workshop print pack: cable labels & CSV BOM

Cut-out cable wraps for lamination (gauge, voltage, protection) + one-click CSV BOM for material ordering.
