What Are The Lithium Battery Requirements For A 5kW Solar System?
Batteries are necessary if you live off the grid to store energy, so you may use them when the sun sets. Your daily consumption and the inverter input will determine your required batteries. Most 5kw solar system off grid contains an inverter that runs 48 volts. You need a 400Ah battery bank if your system generates 20 kilowatts daily. The necessary battery bank will be less as your daily energy usage increases. There are batteries to store any excess power that is not being used. Therefore, the less energy used, the fewer batteries are required.
48V Energy Storage Lithium Battery
The 48V low-voltage energy storage lithium battery product independently developed has a complete set of property rights for R&D, design, and production, and has the following main advantages:
1. Long life and safety
The safe new lithium iron phosphate battery and reasonable and rigorous product design and manufacture make the battery life more than 6000 times (DOD 80%, 0.5C, 25℃).
2. Intelligent
Each battery has an independent and efficient BMS system, which can intelligently and effectively manage power output and comprehensively protect battery safety.
3. Modularization
Each battery can support a maximum of 16 in parallel, and end customers can choose according to their household power consumption.
4. Easy to install and use
Just plug and play to minimize the installation time and cost. The compact and fashionable design fits in your sweet home environment.
5. Compatibility
With RS485, CANBUS, RS232, and other communication protocols, it can be perfectly compatible with all off-grid or hybrid inverter brands.
