Can more batteries give you more stable power

Featured Replies

Setup: Solar + 8KVa Deye Inverter and 2 x Dyness BX51100 Batteries

Last week I installed my second Dyness BX51100 and immediately noticed the evening during load shedding that the power seemed more stable, especially our LED dimmer lights. I also noticed that when one of my many fridges starts that the light dip is now no different to when we have Eskom power, previously it was very noticeable.

Our draw has always been under 80% of the single battery (0,5C 5,12KWh) and now it is 40% of the two combined. I'm also noticing less "dipping" into Eskom grid power during the day when there is clipping on my panels.

Is it possible that the improved stability is from a lower draw of the combined battery pack.

It definitely is. The more battery capacity you have the better. You never have too much. It also lovers current stress on the battery, extends live expectancy.
