Re: Understanding Battery Bank Charging
Finally figured out the Boost and float voltage settings for the Sunny Island. Now the SOC stays stable and only a 0.5C increase in battery temperature.1 · -
Re: Understanding Battery Bank Charging
Interesting how the SI charges the NiFe battery bank at different Boost charging voltages. The first graph shows a "shallow upward slope with a 1.65v (62.7 overall voltage) as opposed to the sec…2 · -
Re: Understanding Battery Bank Charging
Is it ok to keep this constant float charge on the battery bank in float mode, instead of the voltage being turned off and on as the inverter wants to do? Also, this what happens when I turn off the …1 ·
