Your guide to smart, optimal, self-sufficient energy.
Unlike Energy, which is accumulative and is measured in Watt-hours (Wh) or kiloWatt-hours (kWh), Power is instantaneous and is measured in Watts (W) or kiloWatts (kW). Power measures the rate at which Energy is being generated. For example, a 3kW (3000 Watt) solar system is capable of producing 3000…
In a solar system, a battery bank has one important job, and that is to offset 100% of your energy usage. So naturally, when sizing a battery bank for your solar system, your energy usage, among other things, should be taken into consideration. If sized improperly, the battery…
In the summer, with the right weather conditions, a 2kW (2000 Watts) solar system could produce up to 2 kiloWatts (or 2000 Watts) of power, or even more in some cases. However, what really matters at the end of the day, literally, is not the amount of power…
To find the proper wire and fuse (or circuit breaker) sizes for your 3000 Watt inverter, you’ll need to calculate the maximum amp draw of the inverter. This maximum amp draw will generally depend on 2 factors: The efficiency of your inverter. The lowest battery voltage at which…
The amount of current (Amps) that a 1500 Watt inverter draws will mainly depend on the voltage of the battery bank (12V, 24V, or 48V), and the power usage (Watts) of the AC load. However, the wires and over-current protection devices (fuses and circuit breakers) used for the…
The maximum amount of Current (Amps) that a 2000 watt inverter is capable of drawing from the battery will mainly depend on 2 factors: The conversion efficiency of the inverter The voltage rating of the battery bank And in order to size the wires and the fuse (or…
In this article, I discuss the amount of Current (Amps) that a 1000 Watt inverter is capable of pulling from the battery and explain how to use the voltage of your battery bank and the efficiency of your inverter to determine this amount of current. I also discuss…
When trying to figure out what size charge controller you’ll need for your 800W system, you’ll need to consider 3 ratings: The Battery voltages (12V/24V/48V) that the charge controller is designed to operate with. The Output Current rating of the charge controller (in Amps). The Maximum Input Voltage…
The main rating of a solar charge controller is its Output Current rating (in Amps), and this rating represents the maximum amount of current that the charge controller will be able to deliver at its output. However, when sizing a charge controller for your 400W solar panel you’ll…
When sizing a solar charge controller, the main specification to consider is the Output Current rating of the charge controller. For example, a 10 Amp rating means that the maximum amount of current that the charge controller is capable of delivering at its output is 10 Amps. The…
The main rating of a solar charge controller that you should consider is its Output Current rating. The Output Current rating or the “size” of the solar charge controller that you need for your 300w solar panel, will mainly depend on 3 factors: The voltage of your battery…
The size of wire that you need to connect your solar components together will generally depend on 2 variables: The maximum amount of current (Amps) that will be flowing through the wire The length of the wire In this article, you’ll learn how these variables come into play,…
