Off-Grid Hybrid Inverter

Off-Grid Hybrid Inverter is a multi-functional energy device designed for scenarios without grid coverage or independent power supply, the core feature is to operate away from the public power grid, and at the same time integrate multiple energy sources such as photovoltaics, energy storage batteries, and backup generators to achieve stable power supply in an independent power system. Its role can be developed from three core dimensions: "off-grid independent operation", "hybrid energy synergy" and "load assurance".
1. Independent power supply from the grid to solve the needs of no-power/power-shortage scenarios
Core function: In areas without public grid access (such as remote villages, field camps, islands, and communication base stations), an independent power system is built through the combination of "photovoltaic + energy storage" or "photovoltaic + energy storage + generator" to provide stable alternating current for the load.
Applicable Scenarios:
Remote areas not covered by the power grid: replace traditional diesel generators (reduce fuel dependence and pollution), and achieve 24-hour power self-sufficiency through photovoltaic daytime power generation and battery energy storage nighttime power supply;
Areas with unstable power grids: As a "backup core", when the power grid is frequently cut off, it does not need to rely on the power grid, and the power supply is directly guaranteed by its own energy system (such as rural and mountainous areas in some developing countries).
2. Coordinated dispatch of hybrid energy to improve energy efficiency
Multi-energy access and priority management:
Photovoltaic priority: the direct current generated by photovoltaic panels is preferentially used during the day, which is converted into alternating current by the inverter to supply the load, and the excess power is stored in the energy storage battery;
Energy storage supplement: when the photovoltaic power supply is insufficient at night or on rainy days, the power stored by the battery will be automatically released to maintain the load operation;
Backup energy source: When photovoltaic and energy storage are insufficient (such as continuous rain), backup energy sources such as diesel generators can be automatically started to supply power to the load and charge the battery at the same time (to avoid over-discharging the battery).
Dynamically balance load demand: Adjust energy output in real time based on load power (e.g., household electricity, small devices), such as:
When the photovoltaic is sufficient during the day, the 12kW inverter can support the simultaneous operation of high-power equipment such as air conditioners, water pumps, and refrigerators.
When only small loads such as lighting and TV are started at night, the battery discharge power is reduced and the battery life is extended.
3. Ensure the stability of power supply and equipment safety
Stable voltage/frequency: In off-grid scenarios, there is no grid support, and the inverter needs to stabilize the output voltage (such as 220V/380V) and frequency (50Hz/60Hz) through the built-in control system to avoid voltage fluctuations damaging electrical appliances (such as refrigerators and computers).
Battery Protection & Management:
Real-time monitoring of the energy storage battery's power (SOC), temperature, charge and discharge current, to prevent overcharge, overdischarge, short circuit, and prolong the service life of the battery;
It supports different types of batteries (such as lead-acid and lithium batteries), and optimizes the charging and discharging strategies through adaptation algorithms.
Load protection function: with overload, short circuit, over-temperature protection, when the load power exceeds the inverter rating (such as 12kW model with 15kW load) or equipment failure, the output will be automatically cut off to avoid damage to the inverter and load.
4. Adapt to diverse workloads and scenario expansion
