  1. I bought this Adaptor

     

    https://www.ebay.co.uk/itm/392943898051

     

    and downloaded this Android App direct from Epever

    Once the phone is connected to the WiFi Box the readings from the Charge Controller can be read. After changing the Battery Type to User on the Controller the settings can be changed and then sent back to the Controller.

    Which screen module have you got? Is it just lights and buttons, or is there a display?

     

    Have you seen this manual? Page 25 and 31 seem to discuss settings and connections to PC, Phone App, via cables, wifi and bluetooth.

    Like Julian, I have the MT50 display connected to my older EPever, which has no facility for a built in display and no lights and buttons for settings, (2 lights, 1 button).

    That is the manual I got with the unit. The screen has a display and buttons.

  3. I have noted that an additional term has been added to the L2/L3 Mooring agreement:

     

    P12. You must not build any structures, either permanent or non-permanent, at the Mooring Site and over the Trust’s water space.

     

    While I can understand not being able to build anything over the water space, how can CRT dictate what is built on the Private Property?

    No way to alter it that I know of.

    However if you are really worried about it you could remove the temp sensor and just set the voltage using the computer to whatever the average temp was for that season. Whether this would have any unintended consequences I cant say but you would have to reset the voltages probably monthly.

    One downside I can think of is I think that the victron shuts down if the temp is to high and you would lose that safety.

    ETA

    Just realised that there was a load on mine when I looked at the voltage, with load removed it dropped 0.25v did you have a load on yours?

    Only load would be 12v fridge as and when it kicked in. But the 14.8 was constant over several hours.

    You seem to have got your 10s mixed up or missed out the word below. At 10 deg ambient temp then that's 15deg below 25 not 10.

    My batteries are at 17deg at present (measured on solar controller) and are floating (using the Victron combi as its winter) between 14.1/14.2v when set at 13.8v 

    Ill leave you to do the maths.

    Yes sorry I did the maths wrong as you say and I should multiply by 1.5. But that will still give a compensated voltage of 14.65 which is well below what I saw today. Main question is, will I be damaging Gel batteries if they are being charged at up to 14.8V or is there a way to alter this?

    Victron manuals are available to download free from their website. I expect battery type will be selectable by dip switches.

    I have the Victron software but there isn't an option to alter the Temperature Compensation setting. Unless by selecting a different battery type it also alters the Temp setting values?

  7. I have 50A Victron Phoenix charger to charge 4 Exide Sealed Lead Acid batteries. When the batteries need changing I plan to get Trojan Gels. Charger and Batteries are located in the engine room and so I would say close to outside temperature when moored.

     

    Reading the Trojan literature they state that Temperature Compensation should be 0.028V per cell for every 10 degrees below or above 25 degrees. So, if I am correct, at 10 degrees you would need to add 0.028*6= 0.168V. The Absorption Voltage is 14.4 so it should then be at 14.568.

     

    I have my charger set at an Absorption Voltage of 14.4 but when charging today, around 10 degrees, the Voltage is up to 14.8. I cannot find anywhere to set the Victron Compensation so it looks like it is adding >0.04 Vpc per 10 degrees.

     

    When I change to the Gels is this going to be an issue that it is charging at a higher than recommended  voltage or am I worrying too much? If it is, is there anyway to alter the setting on the Victron?

  8. I will be at Autherley Junction and need to get to the southern Grand Union. I came via the Coventry and Staff and Worcs and was going to retrace my route. However in discussion someone suggested the following route:

     

    Stourton

    Black Delph

    Dudley No 1 and then 2

    Netherton Tunnel

    BCN Main Line

    Kings Norton

    Lapworth

     

    I normally cruise 4/5 hours a day and am happy to do more when necessary and don't mind the number of locks. My main concern is finding safe overnight moorings on the route.

     

    Does anyone have any suggestions, advice, places to avoid etc as it will be a totally new route for me and I will be doing it single handed.

     

    Thanks in advance.

    Or moor at bridge 2 on the staffs & worcs and walk over the bridge and straight on across the park to the road, turn left, its on the right.

    This is definitely the best option, Bridge 2 on the Shroppie, just a 5/10 minute walk through a park and a few houses. Perfect thank you.

    That's also what I thought, and the pictures of Bletchley towing Bideford looked to me like Alan was at the tiller on the motor, so I would be surprised if that were not still the case.

    I haven't seen any pictures but I can assure you Jules was steering it through Braunston yesterday!
