Cheapest Ive seen. Site states limited quantity available but unsure on just what number is 'limited' apart from more than 10. Good Luck!
Some specs below that have been borrowed from a previous post ;)
Bluetooth Smart built-in: dongle not needed- The wireless solution to set-up, monitor and update the controller using Apple and Android smartphones, tablets or other devices.
VE.Direct- For a wired data connection to a Color Control panel, PC or other devices
Ultra-fast Maximum Power Point Tracking (MPPT)- Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.
Advanced Maximum Power Point Detection in case of partial shading conditions– If partial shading occurs, two or more maximum power points may be present on the power-voltage curve. Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPP. The innovative BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP.
Outstanding conversion efficiency– No cooling fan. Maximum efficiency exceeds 98%. The full output current up to 40°C (104°F).
Flexible charge algorithm– Fully programmable charge algorithm (see the software page on our website), and eight pre-programmed algorithms, selectable with a rotary switch (see manual for details).
Programming, real-time data and history display options- Modern Apple and Android smartphones, tablets, macbooks and other devices: see the VE.Direct Bluetooth Smart dongle and the MPPT app discovery sheet for screenshots.
Extensive electronic protection- Over-temperature protection and power derating when temperature is high. PV short circuit and PV reverse polarity protection. PV reverse current protection.
Internal temperature sensor- Compensates absorption and float charge voltage for temperature.
Very good price and $20+ cheaper than a month ago
