SRNE MPPT solar charge controller 10A
Why buy this?
- The latest MPPT charge controller with integrated Bluetooth so the solar system can be monitored on an Apple or Android phone.
- Includes load/lighting control.
- Ideal for sheds, campervans and caravans.
Features
Water resistant to IP32 which means it is designed to handle vertical water drips.
Integrated Bluetooth so the solar system can be monitored on your Apple or Android phone without needing to buy additional displays or bluetooth modules.
Load and lighting control for timed control of light circuits and other loads.
Many compatible batteries types including automatic detection of 12 or 24V.
Current restriction which is not a common feature on solar charge controllers. It can be very useful for generating extra power in UK winters.
Look after your LiFePO4 batteries since it is very simple to change the charging parameters if you wish to maximise the life of your batteries. Also has optional low temperature protection.
Multiple protections including solar and battery reverse polarity, solar short-circuit, solar over-current, battery over-voltage, battery over discharge, over and under (LifePO4) temperature protection.
Very quiet due to natural cooling. Other controllers have a fan which may not be ideal in a small environment like in boats, campervans or caravans.
Accreditations
Compliant with Restriction of Hazardous Substances (RoHS) in Electrical and Electronic Equipment.
European CE approved – assessed to meet high safety, health, and environmental protection requirements.
MPPT vs PWM
Charge controllers are either Maximum Power Point Tracking (MPPT) or Pulse Width Modulation (PWM). They can look identical, but have different electronics inside.
Benefits of MPPT
Increased output in partial shade conditions e.g. when there are clouds or partial shade.
More flexible design when matching with solar panels. Can be used with less expensive domestic style solar panels (higher voltage).
More efficient than PWM controllers meaning more energy from the sun being stored in the battery.
Recommendation
Protection measures
App for Android and Apple
Compatibility
- Compatible with lithium batteries including LiFePO4 with customisable charge settings.
- Max solar input is 130W at 12V.
- Max solar voltage is 45V (Open Circuit Voltage – Voc).
- Compatible with 12V and 24V battery systems.
- Not suitable for boats and yachts due to the lower waterproof rating of IP32.
Mike –
Very plastic but no different to the old Victron controller. I hadn’t heard of SRNE before but they are half the price and probably a bit better than the ebay ones! Its working well so far.
