More Solar for "Us"
Ok, I went off.the deep end? Bought 3 used 37watt uni-solar panels and a blue sky 2000e controller for the hefty price of $400, They were being listed as 75w panels, they are not The tested open...
Forum Discussion
If you run your genny first, the voltage of the battery will be such that you will not get the most benefits from your solar and your mppt of the Bluesky.
I would see if a day long solar charge will make it close to the boost setpoint..Or when the amps drop down enough that you make a decision to run the genny for <>1-2 hrs at the end of the day.
Here is a little text from a thread regarding the 2000e and boost etc

Good Evening Barry,
From the 2000E owners manual:

Bulk Charge
Solar Boost 2000E will be in the bulk charge stage when the battery is at a low state of charge, typically less
than 90% full. Solar Boost 2000E delivers as much charge current as possible during bulk to recharge the battery as
rapidly as possible. Maximum charge current varies with the number and size of solar panels installed, available
solar energy, and operation of the proprietary MPPT current boosting system. Battery voltage increases as the
battery recovers charge in the bulk stage. When the battery recovers sufficient charge for battery voltage to reach the
charge voltage setpoint, the system switches to the constant voltage stage. During the bulk charge stage, the Charge
Status LED will be on continuously.
Constant Voltage Charge
Once the battery becomes more than approximately 90% charged, the system changes to a constant voltage
mode and the Charge Status LED blinks. The charge voltage setpoint is factory calibrated to approximately 14.0 volts.
While charge voltage is held constant, charge current slowly decreases as the last 10% or so of battery capacity is
restored. If there was no DC load on the system, output current from Solar Boost 2000E would eventually drop to
approximately the battery amp-hour rating divided by 500, or approximately 0.5 amps for a 230 amp-hour battery.
The precision PWM voltage control method provided by Solar Boost 2000E prevents over charge while maintaining
a more fully charged battery.
