should our 15L fridge be using so much battery?
we bought a campervan from a dealership 6 months ago and have had issues with our battery life since the start. hoping someone with more knowledge than us might have some advice
we have a 100ah deep cycle battery and 15l brass monkey fridge. when we’re not using the fridge the inverter is reading a steady 12.5v and this will stay stable after charging phones etc. but after 5 hours of the fridge being on it’s gone down to 12.2 and continuing to go down. the battery is supposed to last several days without having to drive!
at this voltage the battery struggles to recharge even on a long drive. we have had a new battery, isolator and fridge fitted recently (because the seal was broken) but the issue persists and we are at a bit of a loss now. it feels like the battery isn’t charging as much as it should AND as though the fridge is draining it… is this just normal and we need solar panels or?
