NOMA Charge Controller (maxsolar) Question UPDATE

[BFL13]

UPDATE 22 Sep---I got attacked by the robot monster trying to add a reply, so here is the main answer--2 hours in Absorb, then Float. Ran a test today for that.
--------------------

Asking here in case anybody has one. Got this "kit" today on sale, because I a have a job for it, but I can't find out what the charging profile is for the controller.

How long does it stay in Absorb?

(No real tech support, customer service clueless, they said it is from www.maxsolar.co.in, but their site has no real info in this controller either. )

It is a typical "eBay" PWM 30a controller, but the three stage charging profile is not described in its manual. Absorb and Float voltages are adjustable, which is good.

I want to know how long it stays in Absorb whatever the Vabs is set at before it drops to Float, whatever that is set at. I can find out by doing a test, but it is a pain to set up the test and takes time, so am hoping somebody here might happen to know. Thanks.

Ran a test and it got the battery to my set 14.5 and said Absorb. Held 14.5 for two hours and dropped to my set Float 13.7. OK, same profile EP Solar uses with that two hours in Absorb.

Ha! I snuck that past the robot monster! 😞

Hi BFL13,

That's actually not a bad price--thanks for posting it.

Yes they usually have the 100w on sale for around $200. A real solar shop here has their regular price for a 100w at $190. How CanTire can sell any for 4 or 500 regular is just amazing. People don't have a clue.

So 150 with a controller thrown in is very good indeed. I think the controller would go for about $20 on eBay. It seems ok though. Has two adjustable voltages and has good terminals for the wires (#8 fits)

Weird not to get the controller's charging profile in the manual, just how to set the voltages, etc.
