-Operating Instructions SQ11
-Charging
-Attention! Before using for the first time, fully charge the mini camera
-battery!
-This mini video camera has a built-in lithium-ion battery. You can perform
-charging in one of the following ways:
-. Connect the mini video camera to the USB port of your PC, stop recording
-   first.
-. Connect the mini camera to a charger from a 220V network or a portable 5V
-   charger. In this case, you can continue to use the mini-camera in the
-   charging process. In the charging process, the blue and red LEDs will light
-   constantly.
-After the mini camera battery is fully charged, the blue LED will light
-constantly and the red LED will turn off.
-- If the built-in battery is empty or there is not enough space on the memory
-  card to continue, the blue and red LEDs on the mini camcorder will blink for
-seconds simultaneously, after which the mini camcorder will save the
-  recorded video and automatically turn off.
-- If the memory card is not installed, the blue and red LEDs of the Mini
-  Recorder will blink simultaneously for 5 seconds, after which the Mini Camera
-  will automatically turn off.
-- If the camcorder is in the standby mode and does not take any action on it,
-  the camcorder automatically turns off after 1 minute to save the charge of
-  the built-in battery.
-Video recording
-- Shooting video with a resolution of 1280X720P
-Press the <On / Off> button to turn on the mini camera - the blue LED will
-light up - the mini camcorder is in the video recording standby mode with 720p
-quality. Press the <On / Off> button once to start recording video - the blue

-===== Solar panel stuff =====
-<file text solar_power_system_calc.txt>
-- inverter?
-- battery?
-- solar panel?
-) load calculation
-- assume 4x25w led light, 2x80w fan, 1x40w tube light, 1x50w tv
-- total power = 100w + 160w + 40w + 50w = 350w
-) inverter selection
-- load = 350w (oonsider: 500w)
-- recommended: 800w-1000w
-) battery selection
-- assume 12v dc battery
-- for 350w ac load, i(dc) = 350w/12v = ~30a
-- assume battery operation of 8h
-- battery capacity = 30a x 8h = 240ah
-# 250ah battery available!
-) battery charging current calculation
-- assume 250ah
-- charging current = ~10% current rating (Ah)
-- charging current = 25A
-) solar panel selection
-- solar panel current = charging current + load current = 25 + 30 = 55A
-- solar panel power = 12v x 55A = 660W
-- solar panel options: 125w / 180w / 375w / 440w
-- solar panel count = 660W / 180W = ~4!
