Normal Solar Charger Controller
The MPPT solar charger controller is an affordable, straightforward solar product. It significantly enhances the charging efficiency of solar panels by employing maximum power point tracking technology, thus providing households with a stable power source. Typically, it necessitates an external battery to store energy. Then it outputs direct current to an inverter, producing alternating current for various household appliances. This controller is not only cost-effective but also easy to install and use, allowing more families to effortlessly benefit from solar power systems.
Despite its widespread use and large user base, the solar product had fundamental flaws from its inception:
As shown in the wiring diagram below, this solar controller relies on a battery for energy storage. It cannot function without one, as its primary output is battery-derived.
When sunlight is abundant, the solar panels charge the battery. During this time, the battery cannot discharge and only charges, so the household still relies on mains electricity.
Once the battery is fully charged, it can discharge. However, if solar conditions are still favorable, the battery cannot charge further, wasting the available solar energy.
After the battery’s charge depletes during the day, there is no opportunity to recharge it, rendering it unusable at night.
These issues inconvenience users of solar energy. Imagine a scenario where, after a morning of good sunlight charges the battery, it begins discharging in the afternoon for household appliance use. By evening, the battery level is low, necessitating reliance on mains electricity for lighting, watching TV, and using fans at night. Alternatively, on a day with poor sunlight, the battery charges slowly, and mains electricity is predominantly used.
After prolonged system use, the battery quickly deteriorates in capacity due to daily full charging and discharging, dropping to levels where it can no longer sustain discharge voltage. Replacing the battery can cost several times more than the solar charger controller itself. If replacements are needed frequently, the savings on electricity costs from using solar energy do not offset the battery’s cost.
If we want to solve the above problem, there are two options:
Use a hybrid solar inverter, which tends to be expensive and unaffordable for families with low electricity needs and income;
Increase the number of solar panels to manage periods of insufficient sunlight and enable direct solar drive. However, this also leads to a sharp increase in costs and can produce high voltage or current that does not match the input requirements of the solar charger controller, causing damage.
E-Hybrid Solar Charger Controller
How can we effectively solve the issue of the solar charger controller’s energy needing to pass through the battery without increasing costs? Adding monitoring and management modules to the energy allows the system to autonomously choose its energy sources and outputs. This enables direct solar output, bypassing the battery.
This problem is solved, but how to maintain stable system output when solar energy is insufficient? The solution is to have the battery output automatically supplement only the portion of energy missing from solar power, rather than switching entirely to battery output.
When solar power generation exceeds the real-time load, how can this surplus be utilized? The solution is to allow this excess solar energy to charge the battery.
This approach largely bypasses the battery, keeping it perpetually in standby, not as the primary energy source. E-Hybrid solar charger controller is such a unique and innovative product that redefines the MPPT solar charger controller.
The wiring diagram of the E-Hybrid solar charger controller is as follows. Compared with the normal solar charger controller, it has an independent inverter interface. The inverter of the normal solar charger controller is directly connected from the battery.
There is also a multifunctional DC output, which can achieve different output modes so that every 1W of solar energy can be utilized.
The energy flow direction of E-Hybrid solar charger controller is multiple and complementary. The energy flow of the normal solar charger controller is one-way, making it unusable without battery.
The complementarity of solar energy and battery energy, as well as excess solar energy charging the battery, can be used in a variety of scenarios. The comparison is shown in the figure below:
As mentioned above, we can conclude that E-Hybrid solar charger controller has the following outstanding advantages:
- Solar power utilization rate is 30% higher than common solar systems

E-Hybrid solar charger controller is an economical solution, mainly for general home users. The controller enables most areas to use solar energy at a lower cost and provide a better user experience. This flexible and practical product solution, with low price, will gradually replace the popular normal solar charger controller on the market.
