tombic Do not use more PV power, then optimal. Optimal panel voltage is about 32V for 24V battery and lower current than is rated current of controller. So for 24V battery and 40A model it is about 1200W PV power. You can use panel with higher voltage up to max 50V (then more PV power), but not more current. But you get no more power from that panel. As this is PWM controller, it can't use it.

tombic Yes, options for lead batteries are in the "menu"

tombic Yes. Can be disabled.

tombic This board routes 4 pcie links, so if your motherboard has only one on the PCIE port it will route only one. Depends on your SSD, but AFAIK, it will work, only in 0.25x of the full speed (about old SATA speed).

tombic You need camera gateway (it's own gateway, not zigbee gateway). Camera gateway connects directly to WiFi, or ethernet cable not to xiaomi gateway.

tombic No. Battery is built-in.

tombic It is impractical to measure % of CO2 in air as it is only about 400ppm of CO2 in atmosphere. But you can calculate it yourself. 400ppm is 0.04%. 10000ppm is 1%.

tombic At least receiver compatible with taranis as there is none.

tombic Hi, no, it is 3 phase generator, so each wire is one phase out. Do not tie it together, as it become short, that will effectively brake generator and will burn wires. Let it be unconnected, if you only use one phase. But power of one phase is only one third of total power.

tombic There is small trimmer. Just above grey "box" on the picture.

tombic Yes, only with xiaomi home app.

tombic Xiaomi home app. Internal protocol is not published.

tombic Productpage is manual also, just scroll down, probably everything is explained there. I think, no downloadable manual is available.

tombic Yes. Of course, your cellphone should support OTG + power needed by dongle (about 300mA). SDR driver on google play works ok + some of the SDR apps.
