MakeSkyBlue charge controllers here in the USA.The new V118 is here.
We are here to support you 100%. Upon purchase you will have free tech support. you can google my username and goto our forum with lots of information.
These units can be ran in parallel, very easy to do.
Update: V118 now ships with D06 setting. It enables the user to calibrate voltage If need be. We calibrate each units voltage before shipping with a HP 6654A precision power supply.

What’s different between V118 and fake V113?
The V118 max efficiency is 98.2%.
The V118 MPPT track speed is 5 times faster than V113.
The V118 Charging Voltage Accuracy is ±0.1.
The V118 is better to charge lithium battery.
Notes: The V118 version motherboard is different than V113. Components are more robust.
Between 2/1/2019 and 6/1/2019 653 units have been sold and only 11 returns. of the 11 returns only 3 were damaged to misuse, the other 8 were in working order. That is less than .5% return rate.
Please see v118 advanced function:
1. The advanced application for V118 30A, 40A, 50A and 60A:
If you want to control a big current load such as 100A,
you could use the OU terminals to control it as below pictures.
(Figure 1)：Using a relay to control a small current switch to achieve an inverter switching machine.
(Figure 2)：Use relay to control high current load input circuit-loop.
2. The advanced application for V118 50A and 60A:
your load device is shorted or over-current, the controller will start
output short-circuit protection to close the output condition. When you
the load and press ENT over 5 seconds, then output will turn on again.
Please note that 30A and 40A do not have this function.
3. The advanced application for V118 50A and 60A:
your load device is shorted or over-current, the controller will have
output short-circuit protection and close the output. When you
load and press ENT over 5 seconds, then output will turn on again. Please note the 30A and 40A don’t have this function.
MPPT output of the battery voltage will not rise suddenly, and the
controller doesn’t cause the output voltage to overshoot through the
By the way, the charging voltage of V118 version can be set from 12V to 17V compare to the fake products is from 13.5V to 17V.
The discharge voltage can be set from 9.8V to 14V.
4. The advanced application for V118 30A, 40A, 50A and 60A:
time and light control for OUTPUT will be accurate when you connect the
lamp or other DC loads less 5A. The fake product can’t use the time
and light control and can’t connect other DC load except the lamp.
