OK, as you may have seen from my "EBL99 Stopped working post"; i think i'm all fixed on that now with the EBL99 now repaired and an auxiliary 18A charger added. All appears to be working well.
So now back to my Solar charger upgrade from 10 months ago.
I removed the Sunsaver 6 charger as I began to mistrust it after I observed what it appeared to be doing (monitoring via my Victron BMV600 & a Fox D1 display connected to the Sunsaver). Also I didn't like the way it was 'spliced' into the cables from the EBL to the Batteries
I want to install an MPPT charger & have decided that it will be either the Victron (75/15) or the Votronic (250 Duo). The max solar cells I well ever go to will be 200 W. (currently 100 W)
The Victron is only a single charge output. Good; ..... so really simple to install. But will only charge the Leisure batteries. (I don't want to mess about with wiring / split relays etc... to charge the starter battery)
The Voltronic is dual output but looks a more complex product with; Appliance output; Starter battery output and a (single) connection to an EBL (I don't understand what this connection is for ?)
My view is; I am never stationary at a site for more than 3 days (without being on EHU) for me to worry about needing "solar" to charge the starter battery. i.e. i'm on the move or I connect to EHU.
Therefore I reckon the Victron is quite good enough for me.
HOWEVER: Questions ...... I cannot see any significant advantages in connecting the Victron solar charger to Block 6 of the EBL99. As I believe, all the EBL99 will do is :
1.) If not on EHU, the EBL99 simply passes through the solar charge current (through an internal 15A fuse) to the batteries.
2.) When on EHU, the EBL99 will "see" the solar charger voltage and is likely to only charge the batteries when it's 1st connected (i.e. the initial Boost timed period set in the EBL) and after .... that only when the batteries are demanding more than the solar charger can provide.
So, with an EBL99 & MPPT solar charger I cannot see any disadvantage in connecting straight to the batteries. (the EBL99 will still 'see' the solar charge voltage at the batteries & so will still operate as point 2.) above ... ?)
If i'm mistaken or I am not considering some other important factor(s) .... comments welcome please.
