Re: Raising the Vmp Voltage of Solar Panels to match the charge controller.
Average voltage across 14 different panels "does not matter". It is the specific Imp should match to within 10% (high to low spec.) for each panel, if the panels are in series. And the Vmp …1 · -
Re: What if we connect string with different voltage in parallel ?
More or less, the generic recommendation is that series connections match Imp within 10% (i.e., 7 amp + 7.7 amp panels in series). For parallel connections, Vmp within 10% (18 volt plus 19.8 volt pan…1 · -
Re: How to maintain my batteries while I wait....
You need to get them charged ASAP (if flooded cell lead acid batteries). And if they are warm/hot environment, you may need to recharge them more often than once per month. You need a minimum of 5% t…1 · -

Re: How to connect 18-150watt panel and six 75 watt panel?
Jaymin, First, your GT inverter has an 11 Amp maximum input current (vs the ~2x 7.02 amps of each strings Imp). so you lost ~3 amps there. And next Vmp is temperature dependent. Solar panels are typi…1 ·
