Choosing the right battery is crucial for an efficient and reliable solar energy storage system. A key part of that decision is understanding power specifications. At Y&H, we offer a versatile range of solar lithium batteries designed to meet diverse energy needs. This guide will explain what our common voltage and current ratings—like 12.8V, 25.6V, 51.2V, and currents from 100A to 314A—mean for your home energy storage or commercial solar project.
Decoding the Specifications: Voltage, Current, and Power
The performance of a solar battery is defined by its voltage (V) and capacity, often indicated by current over time (A or Ah). Together, they determine the battery's total energy storage and power delivery capability.
Our product line includes standard voltages of 12.8V, 25.6V, and 51.2V. These voltages are designed to seamlessly match different system scales. For instance, a 12.8V battery is often used in smaller or modular systems, while 51.2V is a mainstream voltage for higher-power hybrid solar systems and off-grid solar systems.
Paired with these voltages are various capacity ratings, with continuous discharge currents ranging from 100A to 314A and beyond. This current rating directly influences how much power you can draw at one time. A higher current rating means the battery can support the simultaneous operation of more or larger appliances—a critical factor for ensuring backup power during outage or running high-consumption devices like water pumps or air conditioning.
Matching Battery Power to Your Needs
The combination of voltage and current creates a spectrum of power solutions. For example, a 51.2V battery with a 200A current rating can deliver significantly more instantaneous power than a 12.8V battery with the same current. This makes the higher-voltage units ideal for whole-house backup power and larger commercial installations.
Our stackable battery designs provide exceptional flexibility. You can connect multiple units of the same voltage to increase your total storage capacity (kWh) for longer energy independence, or configure them to support higher power demands (kW). This modularity allows your system to grow with your needs, whether you're expanding a villa solar system or a business solar solution.
Built for Reliability and Smart Management
Beyond raw specifications, Y&H batteries are engineered for performance and safety. We utilize stable LiFePO4 (lithium iron phosphate) chemistry, known for its long cycle life and superior thermal safety, giving you peace of mind for years of daily use.
Every battery is equipped with an advanced Battery Management System (BMS). This intelligent system is the brain of the battery, providing essential overcharge protection, deep discharge protection, and short circuit protection. It also enables seamless communication with solar inverters and home energy management systems, allowing for optimal charging from your solar panels and intelligent control over your energy flow.
