Total-Energo LLC performs professional drawings of electrical circuits for hybrid solar power plants of any capacity — from private households to large industrial facilities with multiple power sources. Hybrid solar power plants combine solar panels, inverters, batteries, generators and the network — therefore, the circuit must be accurate, logical and meet technical standards.
What does the service include
Single-line circuit of a hybrid solar power plant:
- Solar panels → MPPT → battery → inverter → load;
- Connection to the AC grid (with or without export capability);
- Generator as backup — with manual or automatic transfer switch (ATS).
Switching scenarios:
- Source priorities: PV → battery → generator → network (or other order);
- Logical switching by charge level (SoC), power, time of day;
- Delays, thresholds, circuit duplication to increase reliability.
Load distribution:
- Critical and non-critical lines separately;
- Automatic overload shutdown when the battery charge is low;
- Connection of external systems: lighting, security, pumps, IT loads, etc.
Power supply and battery charging:
- Battery types: AGM, GEL, LiFePO₄;
- Charging schemes from PV, network or generator;
- BMS, temperature compensation, balancing, monitoring.
Generator integration:
- Automatic start (Gen Auto Start);
- Break contactors for protection against backfeed;
- Start logic — by battery charge, load power or manually.
Control and monitoring interfaces:
- Integration with BMS, Cerbo GX, SmartShunt, displays;
- Data transmission: Modbus, Ethernet, Bluetooth;
- Alarms, alarms, event logging.
Graphics and format:
- AutoCAD (DWG), PDF with comments and designations;
- Format: A3 / A4 with title page, symbol table, specification (optional);
- Conventional designations according to IEC, signatures, terminal numbers.
Why order from us
- A hybrid system — is not just a set of devices. We design the logic of their interaction;
- Individual approach: each scheme is created for your configuration and power;
- We have practical experience with Victron, Studer, SMA, Deye, Must, Huawei, Growatt;
- Schemes undergo technical expertise, audit, contractor inspections;
- We envisage phased implementation and the possibility of expansion in the future.
Who is this service suitable for
- Installation companies for complex energy projects;
- Private owners for the "daytime generation— autonomy in the evening";
- Business: shops, farms, offices, service stations — for backup or peak unloading;
- Facility’with generators that want to automate power supply and reduce fuel consumption.
Result for the customer
- A clear single-line diagram with all sources and switching logic;
- Readiness for installation, verification, audit or approval;
- The ability to scale the system without reworking the diagram;
- Increased reliability, safety and efficiency of the hybrid solar power plant.
