Our MPPT Solar Charge Controller is designed to optimize the charging efficiency of solar panels and maximize energy utilization. This intelligent device uses Maximum Power Point Tracking technology to automatically adjust the battery charge voltage to ensure that the solar panel is operating at its highest efficiency to charge the battery.

With the ability to handle a wide range of solar input voltages and battery types, our MPPT solar charge controller provides reliable and efficient charging performance for various solar power systems. The advanced technology also enables better utilization of solar energy, which benefits both the end-user and the environment.#40a mppt solar charge controller

So what happens when you hook up this 130-watt panel to your battery through a regular charge controller?

Unfortunately, what happens is not 130 watts.

Your panel puts out 7.4 amps. Your battery is sitting at 12 volts under charge: 7.4 amps times 12 volts = 88.8 watts.

You lost over 41 watts - but you paid for 130. That 41 watts are not going anywhere,

it just is not being produced because there is a poor match between the panel and the battery.

With a very low battery, say 10.5 volts, it's even worse - you could be losing as much as 35% (11 volts x 7.4 amps = 81.4 watts. You lost about 48 watts. [technical note: that lost power is actually getting converted into heat. It's not actually missing, it's just not usable by the charge controller.
