Four Six Volts with 300w of Solar?
I have Samlex Controller and two Samlex 150 panels set up to a couple Interstate 6v batteries. This seems to work fine. Just wondering if I can stretch to a four 6v battery for a little more stabili...

4x GC2 will work fine with 300 watts solar.
I'd agree only if stipulating that the depth of discharge was no more than 30 to 35%, and one was not boondocking for weeks on end relying only on Solar to recharge.
In such conditions as daily cycling to the 50% range for extended times, then a higher wattage to capacity ratio needs to be utilized to keep the batteries happier.
I got a better cycle per dollar ratio on 198 watts feeding 130Ah of capacity than I did 230AH, but there were some other factors involved such as holding absorption voltage for the required time to reach at least near 100%.
A high solar to capacity ratio makes this time at absorption voltage much more likely to occur, and make for happier longer lasting worry free batteries.
Right no I have 198 watts feeding 90AH of AGM, but I need to give it the high amp recharge every so many cycles from its most depleted state, or it will pack up all its toys and go home, making it not great as a solar only battery.
Charge rate is important and arguably more so when the clock is ticking and the sun is dropping.
