Hello All
I have just setup a small DIY solar system with the following: 24v 300 watt panel, 20ACPY -2420 MPPT solar charger, BMS and battery Bank on 7SP1 of 18650s. No load yet.
Now the system charge the battery to about 45% full and it seems to have stopped charging.
I test the amp flow with the whole system connected and its on producing 0.02Amps, however when i remove the Charger i have upto 1.5 amps. Now to me that say the controller is stuffed, however i have read that a MPPT controller wont run small panels. Only new to Solar i am unsure if that is correct and is the actual control not working.
Second question doi need a charger in such a small system, how safe is it to run it just thru the BMS until i can get a better charger.
Thanks
Andy
