Hi everyone,
iam very new to this topic, i probably have seen nearly all of Wills Videos very interesting, but i see only OFFGrid Setups with the batteries and iam trying to get to the point if its possible to add a battery bank explained in the videos for on ONGRID solar system in addition.
I currently have an ONGRID 14kWP solar installation with a dedicated Inverter just for solar (HUAWEI STL12000) and no battery bank. i charge my EV and other power devices automativally steered with homematic.
The house power installation panel has a 2 way energy counter (IN and OUT) so i can feed into the grid with no problem, but i dont get got rewards for feed in, so i would like to optimize the own consumption. To control the energy flow i have a energy meter connected to a solarlog 300. So my central control unit (Homematic) can switch house devices like heat pumps etc. automatically. the homematic always know the power demand of the complete house in comparison of the solar energy production.
i would like to add a DIY LiFePO Battery Bank to cover the inhouse power draw when no sun is shining.
The buildup of the battery bank itself is clear, but if it comes to the battery charge controller and the inverter to fit into my system, i dont know which one is capable to play in the present solar system i have. the battery bank itself must be charged AC 240V as the present solar converter (Huawei STL12000) has no battery integration port / feature. the charge controller must be controlled somewhere over a webaccess or json, in such way to load the battery when i have sufficient solar power and to draw power from the battery when the house requests it ? i can trigger from my homematic on a webdevice to activate possible charging for instance.
How can it be done, which battery charging unit / inverter is capable of such a feature ?
Do i need to control the inverter also, or is it driven by the demand of the house "automatically".
thx for taking your time to explain.
