Total-Energo LLC offers professional drawing of a single-line and functional diagram of an autonomous solar power plant. Such a set of drawings ensures high-quality installation, subsequent system maintenance and is a mandatory addition to the design documentation for responsible facilities. We take into account all power sources, backup logic, switching modes and technical characteristics of the equipment.
What is included in the service
Single-line electrical diagram of an autonomous solar power plant:
- Solar panels → charge controllers → battery → inverter → load;
- Full operating logic: priorities, switching, control, protection;
- Generator backup connection: ATS, reverse current protection.
Load diagram:
- Separation of lines into critical / non-critical (for Victron, SMA Off-grid, Studer, etc.);
- Automatic shutdown in case of low charge or overload;
- Systems: lighting, communication, servers, security, ventilation, etc.
Battery diagram and control:
- Battery types: AGM, GEL, LiFePO₄, with BMS, protections, balancing;
- Charge controllers, shunts, residual capacity indicators;
- Service points, circuit breakers, connection to the inverter.
Integration with a generator or external AC:
- Manual or automatic switching scheme (MTS/ATS);
- Inverter power supply with a choice between generator and battery;
- Automatic generator start with BMS or inverter.
Protection and automation:
- Automatic circuit breakers, relays, fuses, contactors with appropriate characteristics;
- Protections: short circuit, deep discharge, overvoltage;
- Signaling: light or GSM, system status indication.
Drawings in PDF + DWG formats:
- Designation according to IEC, title page, symbol table;
- Explanation to the diagram to simplify installation and coordination;
- Optional: specification of elements and switching.
Why us
- Over 100 implemented autonomous solar power plants — practical experience, not just theory;
- Schemes that are understandable to engineers, installers, and technical supervision;
- We design real modes: operation from the sun, battery, and generator;
- We work with leading equipment: Victron, Studer, SMA, Must, Deye, KStar, Voltronic, Sacred Sun, Pylontech, BYD, LG Chem;
- We adapt the scheme to the object: even if the part is already installed.
Who is the service suitable for
- Private owners of autonomous houses, summer cottages, ECO-cottages;
- Agricultural facilities, farms, pumping stations, facilities without access to the network;
- Companies and developers of autonomous solutions for power supply of critical facilities.
Result for the customer
- A clear single-line diagram that takes into account all power sources;
- Document for installation, examination, technical specifications or tender;
- Guarantee of safe and correct connection without errors;
- Easy maintenance — all logic and access points are clear;
- Scalability: parallel battery, new inverters, generators.
