Are you certain you have the right battery size in relation to your inverter? Follow the steps below to check your battery size (We will only focus on Lithium LiFePO4 batteries in this tutorial). First of all, find all the technical specifications or data-sheets of your equipment, and then follow these steps:Step 1: Determine the capacity of your inverter in kW (kiloWatt).Step 2: Determine the capacity of your battery in kWh and Ah.Step 3: Determine the C-Rate of your battery. Step 1: Determine the capacity of your inverter in kW (kiloWatt)....
Are you also confused? Is it Lithium Ion or Lithium Iron? And what is LiFePO4? A lithium-ion battery (or Li-Ion) is rechargeable kind of battery with a variety of cathodes, for example, a Lithium Nickel Manganese Cobalt Dioxide (LiNiMnCoO2) cathode for NMC batteries or a Lithium Iron Phosphate (LiFePO4) as a cathode for LiFePO4 (LFP) batteries.LiFePO4 and NMC batteries are currently the most common lithium battery types installed in residential solar installations in the country. A lithium-iron battery is also a...
(Read more about Lithium batteries here) People often claim that Lithium (LiFePO4) batteries are expensive, and although initial costs are higher, Lithium batteries are cheaper over a longer period. In this article, we will try and compare batteries that use Lithium Iron Phosphate (LiFePO4) chemistry with Lead-Acid batteries, in terms of capacity, longevity and price over an extended period of time. We will conclude that LiFePO4 batteries are about 40% cheaper in the long run, next to having a range of other benefits. We...
How to choose your Lithium Battery: A Lithium battery is often the most expensive element in a solar installation, and as a battery is a long term investment, it is important to take into account all aspects of a battery before buying. There are a number of parameters that are important to consider when buying batteries, for example: Voltage and capacity charge / discharge rate (C-rate) Depth of Discharge (DoD%) Life span, warranty and (local) back-up support Expandability Mounting other Voltage and...
