Solar Electrics

5th April ::: ML V=12.56⇖Y=??Wh ML left computer charging over night !
4th April ::: ML V=12.67⇖Y=260Wh
3rd April ::: ML V=12.68⇖Y=280Wh
2nd April :: ML V=12.63⇖Y=230Wh
1st April ::: ML V=12.67⇖Y=230Wh

Proposal

Get Victron that will cope with 116v and 45A

31st March : ML V=12.70   Y=330Wh Removed a solar panel mid afternoon, so only one 250w input.

30th March : ML V=12.64⇖Y=310Wh
29th March : ML V=12.59⇖Y=410Wh
28th March : ML V=12.65⇖Y=510Wh High yield as used electric plane.
27th March : ML V=12.60⇖Y=160Wh Low yield as power not used during day.
26th March : ML V=12.60⇖Y=???Wh
25th March : ML V=12.70⇖Y=220Wh
24th March : ML V=12.74⇖Y=340Wh Used angle grinder so yield is higher.
23rd March : ML V=12.84⇖Y=240Wh
22nd March :ML V=12.68⇖Y=560Wh Used angle grinder so yield is higher.
21st March : ML V=12.82⇖Y=210Wh
20th March : ML V=12.63⇖Y=300Wh
Reset VD as it had started new day before mdnight, this brought the ML upto 12.63 ~could have been higher?

19th March : ML V=12.40⇖Y=290Wh
Strange that the ML is low @ 12.4 and there was 20watts usage overnight

18th March : ML V=12.75⇖Y=160Wh
Must check electrolyte again.
Notable is that the ML is high yet the yeils is only 30w or so about the useage ？？？

17th March : ML V=12.40⇖Y=180Wh
Left router on all night :(

16th March : ML V=12.60⇖Y=160Wh
Although to ML voltage was 12.6 the record shows it was 12.32 when switched off last night and now I have loaded with comp, router and led it is 12.24.
Yield of only 160w but battery was on abs for 2h and float for 8hr
May adjust the abs time span

15th March : ML V=12.70⇖Y=240Wh

Though the last two days yield has been below 320w the 41Ah battery is fully charged with some 145w usage. Maybe smaller batteries is the key.

14th March : ML V=12.72⇖Y=220Wh
？ ML V =12.72 ？ Check elecrtolyte levels. ？
All cell were covered but added aprox 32ml of rain water to each.

13th March : ML V=12.55⇖Y=290Wh
12th March : ML V=12.64⇖Y=360Wh
11th March : ML V=12.56⇖Y=420Wh
10th March : ML V=9.99⇖Y=160Wh
13:20 Changed Battery ~ removed last of Rolls 125AH and temp using a 41AH car battery that Gavin lent me.

9th March ::: ML V=10.03⇖Y=380Wh
8th March ::: ML V=10.13⇖Y=350Wh
7th March ::: ML V=10.01⇖Y=380Wh
6th March ::: ML V=10.20⇖Y=440Wh
5th March ::: ML V=10.01⇖Y=310Wh
4th March ::: ML V=9.97⇖Y=340Wh
3rd March ::: ML V=10.13⇖Y=360Wh
2nd March :: ML V=10.12⇖Y=430Wh
1st March ::: ML V=10.01⇖Y=440Wh

Roger,

In general all our products are designed in The Netherlands and manufactured in Asian countries due to cost price reasons.

You can ask such questions to your supplier, they see the country of origin on the invoice they receive from us.

The SuperPack is made in China , mainly Chinese technology, only to be used in small 12V systems.

The normal Lithium batteries LiFePO4 we offer in 12 and 24 Volt are also manufactured in China, the cells are Chinese lithium cells, we design the balancing system in the battery and the external Ve-Bus BMS you need to use them with our products.

Keep in mind that most of the Lithium cells used in the world come from China, they are the best it looks.

Country of Origin can be manipulated a bit by buying the cells from China and completing the product in another country.

Our 12 and 24v Lithium LiFePO4 can only be used for 12 or 24v applications, for 48v Lithium to be used with our products we recommend third party Lithium batteries like BYD and other brands mentioned on our website.

With best regards,

Jan Klumpenaar, Sales Manager

Using only one 250w panel from 13:00. The other goes to an otherwise unconnected battery.

9th February ::: ML V=10.21↖ Y=50Wh
8th February ::: ML V=10.51↖ Y=550Wh
Strangeness :: Last night ~ after sunset the voltage was 12.43 with computer and router on.

7th February ::: ML V=10.01↖ Y=150Wh
6th February ::: ML V=09.94↖ Y=490Wh
5th February ::: ML V=10.08↖ Y=510Wh
It appears as if all the batteries have a cell shorted as they drop to 10.8 as soon as the charging stops. Very starnge3 thtr they all shorted at the same time.
However this means I am charging at too high a rate now and have dropped the charge voltage by 2v.
Will try and repair the batteries.

---

From 5th Feb the charging voltage is 13.92 so the solar input will be low. The available power could have been more than 1Kw
