What is the recommended charge current for flooded lead-acid batteries?The recommended charge current for flooded deep cycle lead-acid batteries is 10 percent of the 20 Hr Amp-Hour or C/20 rate of the battery bank. As an example, if the battery bank is 500 AH total, the output from the charge source should reach 50A during peak charge times (4-5 hours mid-day) to ensure the batteries reach full state-of-charge.
What happens if battery capacity is insufficient?When battery capacity is insufficient to support an increase in usage, an additional parallel string of batteries or larger battery bank may be installed. In this case, the charge source may also require an increase in size to support the required charge current. Additional PV modules may be required to increase the charge current.
What happens if I exceed the PV array input current limit?If you exceed the PV array input current limit AND connect the PV array in REVERSE POLARITY, then there is likelihood of damage to the MPPT, and this damage in not a manufacturing fault and will not be covered by warranty.
What happens if a battery voltage drops below 12 volts?If the voltage drops below ~12.7 volts, the battery supplies current to keep the voltage in range. If it is above ~12.7 volts, the battery absorbs the extra current instead. Most MPPT charge controllers are "relatively" slow (cannot respond instantly to changing loads).
How much voltage should a PV array have?Thenominal PV voltage should be at least5Vhigher than the battery voltage. ThePV array can consistofmono- orpoly-crystalline panels. If I build a system based on these instructions, I could end up with a configuration that does not meet spec. Consequently, there should be another bullet about not violating Isc.
What happens if you oversize a battery bank?Oversizing the battery bank will also cause problems as the batteries must be adequately discharged and charged or “exercised” to maintain their performan
