**Product Features:**
1. Working voltage: 10V - 22V.
2. Built-in MPPT controller to maximize solar energy usage.
3. Over-voltage and under-voltage protection. When the voltage is too high or low, the pump automatically stops. It checks every 10 minutes, and resumes operation once the voltage returns to 10V - 22V.
4. Can be directly connected to a solar panel without a controller in sunlight.
**Solar Panel Recommendations:**
1. For a 12V system, use a single or polycrystalline solar panel with an open circuit voltage (Voc) of around 18V and a maximum power point voltage (Vmp) of about 22V, connected in parallel.
2. For a 24V system, use a solar panel with Voc of about 36V and Vmp of around 44V, also in parallel.
3. For a 48V system, use two sets of panels in series, each with Voc of 36V and Vmp of 44V, connected in parallel.
**Installation Guide:**
1. If the pump operates only during daylight, connect it directly to the solar panel without a controller. A total of about 300W (18V) of solar panels is recommended.
2. If the pump needs to operate at night or on cloudy days, use a battery and a controller for continuous performance.
**Important Notes:**
1. Do not connect the positive and negative terminals of the pump incorrectly.
2. The pump should not run dry for long periods.
3. Ensure the pump is fully submerged in water at all times.
4. For cable lengths over 30 meters, use 6mm² or 10mm² pure copper cables.
5. Avoid using pipes smaller than 25mm in diameter. Bending or reducing the outlet diameter can increase head pressure, causing excessive current and potential motor damage. This kind of damage is not covered under warranty.
6. Never exceed the rated head of the pump.

This sewage solar pump is ideal for remote areas where traditional power sources are unavailable. It’s perfect for irrigation, wastewater management, and water supply systems. With its durable design and efficient solar operation, it ensures reliable performance even in challenging conditions.WELDING ELECTRODE:
The welding rod is composed of two parts: the welding core and the coating. The welding rod is to apply the coating (drug skin) evenly and centripetally on the welding core outside the metal welding core. Different types of welding rods have different welding cores. The welding core is the metal core of the welding rod. In order to ensure the quality and performance of the weld, there are strict regulations on the content of each metal element in the welding core, especially for the content of harmful impurities (such as sulfur, phosphorus, etc.). Limits, superior to base metal.
