Thanks will see what happens.

Thanks Coulomb, I have a bit of a typo in  16 it should be Sbl (solar for batteries first), Udc (disallow utility to charge batteries) however this still has the utility putting in 2 A until the PV power comes on line with the sun. 

There is a setting: Slb (solar for load first), Udc (disallow utility to charge batteries) I could change to this and see what happens, just nervous to change settings the installer made as it may invalidate my warranty.

As for 12 the book recommends 46 Volts the installer put in 47, I understand from you it should be 49 v to prolong battery life.

What do you recommend for 29, the book says 42 V.

Thanks

Hi I am new to this and i wish to get some advice from the knowledgeable users.

I have a 5 kW Synapse unit with 12 x 330 W  panels and 4 x 225 Ah Varta lead acid batteries connected in series.

in the day I have an excess of power, at night I have to use the grid by early in the morning. the problem with this is that the batteries start charging at 2 amps and I would like them to not charge until the cells come in to charge.

My settings are 01=Sbu,  02 = 60 A,  05 = Use,  06 = Lre,  07 =Tre,  09 = 50,  10 = Avt,  11 = 2,  12 = 47,  13 = 54,  16 = Sbl. Udc,  23 =Bye,  26 = 58.4,  27 =56.8,  29 = 46,

Thanks.
