About this product


  • Ideal for connecting 12V solar panels to 1 or 2 batteries
  • Separately charges 2 batteries
  • Maximum charging capability: 2 x 8A or 1 x 16A

Product overview

• Ideal for connecting 12V solar panels to 1 or 2 batteries• Separately charges 2 batteries• Maximum charging capability: 2 x 8A or 1 x 16A• The battery with the lowest charging voltage will receive more charging current• LED status lights• Power consumption of <2mA is taken from the battery• Reverse current protected (no additional diode required)

The maximum charge current is a total of 16A. Two batteries with a maximum of 8A each or 1 battery can be connected in parallel to both outputs up to a maximum of 16A. If you are connecting only one battery, it must be connected to connection 2. There are 3 LED lights, one to show that battery one is charging, one to show that battery two is charging and one to show that both batteries are fully charged. An F16A fuse is required, but not supplied.

Rated 5 out of 5 by from The regulator works perfecly.Monitoring the battery voltage with a multimeter it rises to 14V and the charging lights go out and the accumulator full light goes on.The specification is 14.2 volts +/- 5%.The battery voltage drops to 13V immediately and settles to 12.8 after an hour.A six cell battery is fully charged at 12.7 volts.A 16 Amp capacity is good value for money with the added bonus of being able to expand your storage capacity by adding a second battery to your system particularly if your inverter can connect to 2 batteries.The Kemo web-site stresses correct insulation.If attached to a heat-sink for 4 amp+ operation it must be with screws with heads which fit into the 4 corner recesses.Maybe Kemo or Maplins should market an installation kit with heat-sink, mounting screws,fuse, and fuse-holder.

Rated 5 out of 5 by from I brought this regulator for my Motor home Solar set up. 1x80w & 1x40w - they are Polycrystal type, connected in para, and I have tried PMW /MPPT regulators with the panels , before deciding to stick to using this Kemo unit. The vehicle battery is a 90w Bosch and the 2 leisure batteries are 100w Elecsols. I have the vehicle battery connected to regulator output 1 and the 2 leisure batteries are connected to each other in para and then connected to output 2 as one large battery viz "+" of 1 Leisure battery connected to the "+" of regulator output 2 and the "-" of the other battery connected to the "-" terminal of the regulator. TO do this it's necessary to modify the negative terminal of the regulator by connecting a connector that will allow two "-" connections. I have added a 15amp fuse upstream of the regulator , and I have also connected a 5amp fuse between the output 1 of the regulator and the vehicle battery. Similiarly I have addeda 7.5 amp fuse between output 2 of the regulator and the connecting wire to the leisure batteries. The additional fuses allow me to isolate parts of the circuit and trace any faults quickly. The regulator has performed faultlessly - all three batteries are kept in full condition. I have nothing but praise for this regulator - an improvement would be to replace the spade connectors with screw terminals - but that apart it's a very good regulator.

Rated 5 out of 5 by from Very good! I found nothing to be wrong with the markings, took seconds to wire up, only 5 wires, simple. All I can suggest is read the manual...

Rated 3 out of 5 by from I bought this as a smaller alternative to the regulator that came with the 60w kit (N23FY). The original was the size of two house bricks! After installation I found that the battery connection markings on this unit were marked the wrong way around (- was + & + was -). So I only give it 3 stars, otherwise seems ok!

Rated 4 out of 5 by from An improvement on the previous excellence I had the previous model on my boat for the last 6 years. Now with LED indicators I can check if all is well. These little bits of kit mean that you can use Solar panels to their optimum and separately charge a large battery bank with minimal losses

Rated 3 out of 5 by from I bought one of these after a smaller one stopped working after 11mths. This one lasted longer, 12mths charging 2 x 6v 6Ah batteries from a 12V Maplin Solar Panel. I'd love to have one last more than a year. I was hoping it was only the LED's but the batteries stopped charging through the regulator but charged direct from the panel.

I plan to connect another panel of similar size in parallel. will this be OK? I am charging a leisure battery I use for lighting in my chalet.

Asked by: Dairich
Unfortunately, I would not be able to give any advice due to lack of information as long as you do not exceed the max amps of the item and wire it correctly this should work.

Hi would this regulator be suitable to regulate a 6volt 10 watt solar panel with a 9volt output connected to a6volt motorcycle battery

Asked by: Taffy
This would not be suitible for use with 6v systems.

Can this unit be connected to the output from an existing solar controller to split to 2 batteries?

Asked by: Hugh
Unfortunately we are unable to guarantee full compatibility for this item in your intended application, as this is not the manner for which it was designed to be used.

I want to keep an engine start and separate house batteries topped up over winter by solar panel. They are gell type &amp; have slightly different operating voltages to each other. Is the Kemo M174 a suitable regulator?

Asked by: John B
Yes as long as the output from your solar array does not exceed the maximum amperage of the regulator.
