SEPCO

SEPCO solar power kits typically include sealed lead-acid batteries, such as absorbed glass mat (AGM) or gel cell types, depending on the model. For example, the GPA50-S-ALC1 kit includes an 82 Ah battery. Higher-capacity kits like the GPA340-Q-ALC2 may use lithium iron phosphate (LiFePO4) batteries for longer cycle life and lighter weight. The specific battery chemistry is listed in the manufacturer’s datasheet for each SKU. All batteries are designed for deep-cycle operation and are pre-configured with the charge controller for optimal charging parameters.

Yes, SEPCO solar power kits are designed for continuous off-grid operation, but the load must be sized appropriately relative to the system’s solar panel wattage and battery capacity. For example, a 170 W kit with a battery can power a 20 W load for approximately 8-10 hours per night, depending on solar insolation. The MPPT charge controller maximizes energy harvest during daylight hours. For 24/7 loads, the system must be sized to account for nighttime battery discharge and daytime recharge. SEPCO provides load calculation tools in their technical documentation to assist with sizing.

The lifespan of the battery in a SEPCO solar power kit depends on the battery chemistry and depth of discharge. Sealed lead-acid batteries (AGM or gel) typically last 3-5 years in cyclic service if discharged to 50% depth of discharge daily. Lithium iron phosphate batteries, used in some models, can last 5-10 years or more with proper charge management. The charge controller in SEPCO kits includes low-voltage disconnect to prevent over-discharge, which extends battery life. Ambient temperature also affects lifespan; higher temperatures accelerate degradation.

Yes, SEPCO solar power kits are designed for outdoor installation. The solar panels are rated for exposure to rain, snow, and UV radiation. The battery enclosure and charge controller are typically housed in a weatherproof enclosure with an IP65 or higher rating, protecting against dust and water jets. The kits include mounting brackets and hardware for pole or ground mounting. However, the specific IP rating varies by model; refer to the manufacturer’s datasheet for the exact enclosure rating of each SKU.

The maximum power point (MPP) rating on SEPCO solar power kits refers to the peak power output of the solar panel under standard test conditions (1000 W/m² irradiance, 25°C cell temperature). For example, the GPA170-DM-ALC1 kit has a 170 W MPP. The MPPT charge controller adjusts the operating voltage to extract the maximum available power from the panel, which is especially beneficial in partial shading or varying light conditions. The actual power output will vary with solar irradiance and temperature.
