From 037f3a16d6a3dbadf07572ee05d82bdb236a0794 Mon Sep 17 00:00:00 2001 From: Stuart Longland Date: Mon, 1 Oct 2018 10:08:46 +1000 Subject: [PATCH] setpoints: Drop solar to 4V, battery to 12.75V Reduce the solar threshold so that we're at the point where the SSR can work properly. i.e. we're at first light. The battery can discharge for an hour or two at this point, which will give it a break from the charger just before sunrise. This may trigger the other charge controller to charge the battery during the day. Drop the battery voltage just a fraction so we are past the "knee" of the discharge curve at 12.8V. --- setpoints.h.dist | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/setpoints.h.dist b/setpoints.h.dist index 3c72001..75bba4f 100644 --- a/setpoints.h.dist +++ b/setpoints.h.dist @@ -63,7 +63,7 @@ * should turn the charger on if it remains below this level for T_LOW_S * seconds. */ -#define V_L_MV (12800) +#define V_L_MV (12750) /*! * Critical Low battery voltage.
