Is 12v or 24v Better for LED Lights?

Here’s how to choose between 12V and 24V based on your usage, wiring distance, current needs, and system compatibility:

• 12V carries higher current, runs hotter, and loses more power – bad for long-distance wiring.
• 24V uses lower current, stays cooler, and loses less power. It’s more efficient and better for long runs.

How Many 24v Batteries Do I Need for a 3000 Watt Inverter?

The number of batteries depends on the battery capacity:

Current = Power ÷ Voltage = 3000W ÷ 24V = 125A

So, when the inverter runs at full load, the current is 125A.

Battery capacity = Current × Time = 125A × 1h = 125Ah

You need at least one 24V 125Ah battery to run the inverter for 1 hour.

– For a 24V 100Ah battery, you’ll need two in parallel.

– A single 24V 150Ah battery can power the inverter for 1 hour.

– Similarly, one 24V 250Ah battery runs a 3000W inverter for 2 hours.

This is based on ideal conditions. In real use, you also need to consider depth of discharge, losses, and other factors.

How Long Will a 24v Battery Last with an Inverter?

We need to know both the battery capacity and inverter load power to calculate. Here’s the formula:

Runtime (hours) = Battery Capacity (Ah) × Voltage (V) × Efficiency ÷ Inverter Power (W)

Let’s say you have a 24V 100Ah battery powering a 1000W inverter at 90% efficiency.

This setup would run for about 2.16 hours.

Of course, real-world factors like discharge depth, temperature, and battery age will affect runtime.

How Long Does a 24v Ride-On Battery Last?

The runtime depends on battery capacity and motor power.

A 24V 10Ah battery running a 250W motor lasts about 57 minutes.

24V × 10Ah = 240Wh

240Wh ÷ 250W ≈ 0.96h ≈ 57 minutes

If the speed is 20 km/h, the vehicle can go about 19 kilometers.

Of course, the heavier the rider, the faster the battery drains. More uphill roads also use more power. You should keep these factors in mind when choosing a battery.
