Choosing the right wire sizes in your Solar PV system is essential for both performance and safety reasons. If the wires are undersized, there will be a significant voltage drop in the wires resulting in substantial power loss. Also, if the wires are undersized, there is a risk that the wires may heat up to the point in which a fire may result.
At the heart of any solar PV system sits the battery bank; the battery bank can be either a single or multiple batteries connected to each other. Batteries are connected to each other in order to increase:- the battery voltage (in Volts, V), or- the battery capacity (in Ampere hours, Ah), or- both capacity and voltage.(Power = Volts x Ampere, or W = V x A). You can connect batteries either in series or in parallel. The following happens when batteries...
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...
