This is the story of Mathias Boer-Mah, a self-confessed tinkerer, energy nerd and SolarEdge Home Battery owner. Mathias wanted more control of his battery than SolarEdge could provide, so he hooked up his SolarEdge inverter to a free open-source software application for home automation.
The solar to battery charging efficiency was 8.5%, which was nearly the same as the solar cell efficiency, leading to potential loss-free energy transfer to the battery. Alternatively, an external MPPT or charge controller can be used that would offer a better and efficient control of the integrated system by facilitating maximum PV power

As a general rule, it is safe to trickle charge at a 10% rate, meaning your input current can be up to 10% of the battery''s rated capacity. This is called a C/10 rate. For example, if a battery is rated at 2100 mAh, the C/10 rate would be 210 mA. A few important tips. Note the storage capacity of each battery you are using.
2.2 Why solar charge controller Typically, a common battery charger is required to control the current to the battery with an optimal rate, and to cease charging when the battery is fully charged.
