WHAT ARE SOLAR CHARGE CONTROLLERS?
The charge controller in your solar installation sits between the energy source (solar panels) and storage (batteries). Charge controllers prevent your batteries from being overcharged by limiting the amount and rate of charge to your batteries. They also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity and charge the batteries at the correct voltage level. This helps preserve the life and health of the batteries.
HOW DO SOLAR CHARGE CONTROLLERS WORK?
Regarding “what does a solar charge controller do”, most charge controllers has a charge current passing through a semiconductor which acts like a valve a to control the current. Charge controllers also prevent your batteries from being overcharged by reducing the flow of energy to the battery once it reaches a specific voltage. Overcharging batteries can be particularly damaging to the battery itself so charge controllers are especially crucial.
Charge controllers also offer some other important functions,including overcharge/over discharge/overheat/reverse/overload/short-circuit protection
- Overcharge/over discharge: When overcharging or discharging, a function is needed to protect the battery from damage caused by overcharging and discharging.
- Overheat：During the operation of the controller, the heat generated by the current needs to be released, so it is required that the controller has temperature detection and protection functions to prevent overheating from causing fires
- Overload：Charge controllers provide the important function of overload protection. If the current flowing into your batteries is much higher than what the circuit can deal with, your system may overload. This can lead to overheating or even fires. Charge controllers prevent these overloads from occurring. In larger systems, we also recommend a double safety protection with circuit breakers or fuses....
The MPPT solar charge controller is a type of dc to dc charge controller with electronic protection and adaptive charging functions. It continuously adjusts the electrical load to ensure that solar panels operate at their maximum power point (MPP), thereby improving the efficiency of the solar energy system. Therefore, we also refer to it as an MPPT solar charge regulator.
In photovoltaic (PV) solar power generation systems, the MPPT charge controller plays a crucial role in grid-tied, off-grid and hybrid solar energy systems. It allows solar panels to operate at their highest efficiency, increasing the energy output of the system.
Whether in variable sunlight conditions or extreme environments, Ampinvt’s MPPT solar charge controller enhances the operational efficiency of solar power systems to the fullest by tracking the MPP and continuously adjusting the electrical load.
Our MPPT solar controller is compatible with sealed, gel, flooded and lithium batteries, with a maximum efficiency of up to 99%. Additionally, it also supports WiFi or Bluetooth remote control for convenient and quick operation.
