Overview of Hybrid Solar Power Systems
A hybrid solar power system mixes features of grid-connected and standalone systems, plus battery storage. This mix lets you get the most from solar power, save extra energy, and keep supply steady during blackouts or high demand times.
Fundamental Components and Architecture
A hybrid inverter merges the roles of a solar inverter and a battery inverter into one unit. So, it handles power from solar arrays, storage, and the grid. The main parts of a hybrid system are photovoltaic panels that make DC power, hybrid inverters that manage two-way changes, lithium-based batteries, and grid links for power in and out.
The inverter uses a DC-coupled approach, combining the PV inverter and two-way converter into a single PV-storage unit. This setup allows AC/DC coupling, which supports flexible energy handling. Plus, a built-in EMS (Energy Management System) keeps watch on power flows to improve charging, discharging, and grid ties in real time.
Operational Principles and Energy Flow
In daytime, solar power goes first to meet current needs. Extra energy fills the batteries through MPPT (Maximum Power Point Tracking), which gets the best output and turns DC voltage to the right level for battery charging. When batteries are full, leftover power can go to the grid.
During weak sun or night, stored power comes out to cover local needs. Even more, if sun is low, a hybrid inverter can pull power from the grid to charge batteries, keeping things running. The grid serves as backup and steady source, allowing smooth shifts during voltage or frequency issues.
Advantages Over Conventional Systems
Hybrid systems give energy freedom by letting you use your own power at off-peak times or during cuts in supply. The hybrid inverter smartly balances the whole setup to keep it safe, even with changing solar input. You gain from shifting loads, which cuts bills by saving cheap power and using it in costly peak periods.
Also, these systems hold up key loads in blackouts with quick switchover, under 10ms as in the 100kW 201kWh Hybrid Solarenergiesystem.
Inverter Design Considerations for Hybrid Solar Systems
A good hybrid inverter ensures the system stays dependable and adjusts to changing grid and load situations. This part looks at main needs and design points.
Key Functional Requirements of Hybrid Inverters
Hybrid inverters are a fresh tech in solar energy. They blend benefits of standard inverters with battery flexibility. A strong hybrid inverter needs two-way conversion for PV-to-load (DC to AC) and battery charge/discharge (AC to DC). It must match grid rules in real time for voltage and frequency.
Newer systems use smart load priority rules that change based on use patterns. These keep things steady, even with big inductive loads, as seen in WonVolt’s 50kW 55.3kWh–100kWh Hybrid Solar Power System.
Electrical Performance Specifications
Inverter performance shows in change efficiency (often over 98%), MPPT range fit, and voltage match for PV modules and batteries. Low Total Harmonic Distortion (THD) is vital for good power quality on sensitive gear.
Heat handling matters too; smart designs use passive or active cooling with IP65-rated cases for lasting use in varied weather.
Integration mit Batteriespeichersystemen
Lithium-ion and LiFePO4 types lead in use for their long cycles and heat safety. Given battery life, cost, safety, and charge/discharge efficiency, lithium iron phosphate batteries fit well here.
Links to BMS (Battery Management Systems) use standard ways like CAN or RS485. Smart charge/discharge plans extend cycle life by setting depth-of-discharge limits from real-time use.
Performance Parameters Impacting System Efficiency
Besides part-level design, system efficiency depends on how power gets managed, shared, and saved in different weather and work conditions.
Conversion Efficiency and Power Losses
Inverter losses happen in DC-AC changes and idle times at night or low loads. High-efficiency units cut idle losses with very low standby use, while heat systems stop overheating in full loads.
Voltage drop curves need note, especially in heat; they affect PV power collection directly.
Load Management and Demand Response Capabilities
Good EMS tools predict load actions with data forecasts to apply peak cut strategies. These cover smart timing for devices or factory gear based on live tariff info or grid frequency shifts.
Some setups join virtual power plants by sending extra stored power to smart grids under response deals.
Environmental Durability and Reliability Metrics
For outside use, high protection like IP65 or better blocks dust, water, or rust. MTBF (Mean Time Between Failures) measures long-term dependability.
Systems like WonVolt’s utility-scale containerized BESS solutions include extra cooling and auto fire control for better safety in big setups.
Application Scenarios Using WonVolt Hybrid Solar Power Solutions
Hybrid solar power systems adapt to many fields based on power size, self-run goals, and rules.
Industrial & Commercial Applications with 100kW 201kWh System
The 100kW system pairs strong N-type TOPCon solar panels with a 100kW hybrid inverter and 201kWh lithium battery set. It handles smooth outage shifts (under 10ms) and grows to 300kW in parallel, great for heavy uses like plants or warehouses. Built-in EMS cuts peak costs for lower bills.
Medium-Sized Enterprises Utilizing 50kW 55.3kWh–100kWh System
Mid-size spots like clinics or schools gain from the 50kW Hybrid Solar Power System. It runs steady off-grid, controls export to avoid grid flow breaks, and adds storage for better backup in cuts.
Utility Scale Deployment Potential Across Microgrid Projects
Large systems fit well with spread-out grids in rural power or island cases. Their high inverter efficiency cuts loss over lines while balancing loads in microgrids. Photovoltaic off-grid energy storage system can be installed and used as long as there is sunshine.
