Electricity has many measurement units, such as: Volts, which measure Electrical Potential, or simply voltage. Amps, which measure Electrical Current. Watts or kiloWatts, which measure Electrical Power. Watt-hours or kiloWatt-hours, which measure Electrical Energy. The 4kW (4000W) rating of a…
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…
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…
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…
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…
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…
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…
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…
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…
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…
