Total-Energo LLC performs professional drawing of single-line electrical circuits of guaranteed power supply systems of a closed loop — where the admissibility of power outages is close to zero. We design solutions in which inverters, batteries, generators, external network and solar power plants operate in a coherent logic, ensuring 100% redundancy even in the most complex emergency scenarios.
What is a guaranteed power supply system of a closed loop
This is a multi-level system that includes:
- Main power source (grid or solar power plant);
- Buffer — inverter and battery;
- Backup power — diesel or gasoline generator;
- Automatic switching logic and control system;
- 24/7 signaling and monitoring.
Goal: to ensure uninterrupted power supply to critical consumers even in the event of a complete network loss.
What the drawing service includes
Single-line diagram:
- All power sources: network, generator, solar power plant, inverter, battery;
- Critical and non-critical load lines with designation;
- Source priority, backup logic and switching.
Emergency scenarios:
- Automatic generator start (Gen Auto Start);
- Load control depending on the battery charge;
- Clear programming of delays, intervals and priorities during switching.
Protections and priorities:
- Main power supply circuit: network → inverter → Battery;
- Backup branch: generator or PV + battery;
- Power limitation, reverse current protection, phase synchronization.
Integration with equipment:
- Inverters: Victron, Studer, SMA, Huawei and others;
- UPS, ATS, BMS, external switchboards;
- Batteries: AGM / GEL / LiFePO₄ with BMS and deep cycle;
- Generators: with autostart, external tanks, monitoring.
Monitoring and control:
- Displays, Cerbo GX, charge controllers;
- Dry Contact, Modbus, Ethernet, remote control;
- Logging, signaling, emergency messages.
Drawing format:
- DWG (AutoCAD), PDF A3 / A4 format;
- Title page, symbols, equipment specification (optional).
Why should you order from LLC «Total-Energo»
