Confirm voltage, phase, total running load, simultaneous start-up loads, backup hours and 배터리 capacity before selecting a model. Motors, pumps, refrigerators and air conditioners need extra surge margin.
A complete system usually includes solar panels, an off-grid or hybrid inverter, LiFePO4 batteries, mounting brackets, cables, protection switches and installation accessories. The final list depends on your project.
Off-grid systems can work without utility power and rely on solar plus batteries. Grid-tie systems usually require the local grid. If you only need backup during outages, choose an off-grid or hybrid backup solution.
예, if the load, 배터리 capacity and solar array are sized correctly. High-power loads such as air conditioners, heaters and pumps will require larger 배터리 capacity and higher system cost.
예, but inverter power and starting surge must be checked carefully. One small AC may use a 3–5kW system, while two AC units may require an 8–11kW inverter or larger depending on the model.
아니요. A larger inverter is not always the best choice. Select by continuous load, safety margin and surge power. Oversizing too much can increase cost and reduce efficiency.
배터리 size depends on backup time. A simple estimate is: 배터리 kWh = load kW × hours ÷ DOD ÷ system efficiency. For example, 2kW 용 4 hours usually needs around 9–14kWh depending on assumptions.
PV array size depends on daily energy use and peak sun hours. A rough estimate is daily kWh ÷ effective sun hours ÷ 0.75. For example, 20kWh per day with 5 sun hours may need around 5.3kW or more.
예, but solar generation will drop. If you need 2–3 rainy days of autonomy, choose a larger 배터리 bank or keep generator/grid backup as an option.
예, but parallel operation and expansion must be confirmed by model. 인버터s and batteries need compatible voltage, communication and parallel protocols.
배터리 compatibility must match voltage, charge/discharge current and communication protocol. Please confirm before purchase to avoid protection or communication issues.
Most listed products are solar energy storage or backup systems. Grid-tie requirements vary by country and utility rules, so they need separate confirmation.
보증 terms should be confirmed in the quotation or contract. They depend on product model, order quantity, application environment and shipping arrangement.
Solar storage systems require correct matching of inverter, 배터리, BMS, protection, installation and after-sales support. The advantage is integrated solution capability, not only a low price.
