Eight weather-protected two-pin keyed quick connectors To solve this problem and to optimize the energy performance of the entire system, it is advisable to wire two panels in series (obtaining a doubling of the voltage) and then wire in parallel the three pairs previously wired in series (so as to have doubled the voltage and tripled the current). With regard to reverse current in solar panels, it is useful to know that recent studies conducted by the prestigious Fraunhofer Institute for Solar Energy Systems ISE have shown that solar panels are able to withstand reverse current up to seven times higher than the short circuit current, without suffering any damage. Finally, we will provide you with valid and practical tips to get an efficient system that is fully protected against possible damage due to faults or short circuits that can occur on individual solar panels. Product Weight 33.40 lb. The same voltage of 13.8 from the charge controller can charge all the battery connected in parallel. My van has some weak short-circuit and slowly drains the battery, and as I don’t use the van all that often, I was at risk of coming out to a completely drained battery. On the other hand, if our two solar panels have both different wattage and different voltage, then parallel connection is not possible, since the panel with the lowest voltage would behave like a load, and would begin to absorb current instead of producing it, with the relative consequences.
