Those lead acid batteries release hydrogen gas when charging and from the looks of things, there is no ventilation which is supposed to release these gas accumulation. It’s important to note that hydrogen gas is highly combustible and will burn in the presence of oxygen explosively. Therefore, safety precautions such as adequate ventilation and avoidance of naked fires or sparking are necessary when charging lead-acid batteries.
Hello we have attempted to fix/ upgrade our solar system to accommodate our family to no avail. We are Army Veterans that decided to move totally off grid with our 3 kids. Despite our efforts we have problems when we get very little sunshine. It seems the batteries aren't charged enough to take us through the night. On an average day the sun would have charged our system and the inverter will go into the night displaying 50 volts. However, during a heavy rain we had 2 days ago that started at 9am and lasted all day, we went into the night at 44 volts! By midnight the alarm was sounding on the inverter and the power went off shortly thereafter. We also have this issue when we attempt to turn on the air conditioning...using it too close to sun down can cause the same issue. I was thinking we need a larger battery bank but someone told me I need more panels. Honestly I'm confused. Please help.
