Q: Why are MPPT not more common in standalone solar systems?
Until now and despite their overwhelming advantages MPPTs have not been commonly used
in standalone solar systems because of cost. The new GSL MPPT specifically addresses
this issue making economic sense in a wide range of solar systems.
Q: What sort of batteries should I use?
1.
A deep cycle battery is a must due to the cyclical nature of the solar system with a
recommended battery capacity of at least 180AH.
2.
A larger battery will not only give longer run time during low light but also will be able to
avoid available PV power being unstored such as when battery reaches the float stage.
Q: How do PV temperatures affects charge current?
Temperature increase brings down the PVs maximum power point voltage reducing the
MPPTs current gain available. In principle at 25C it is possible to achieve 30% gain but at
40C, a more realistic average temperature, about 20% is still available.
Q: What happens at low PV currents?
The MPPT will outperform the conventional regulator above 3% of nominal panel power.
Below 3%, about 10W in a 400W panel, the MPPT will have a slightly lower output current
than a non MPPT.
