1- 12v vs 24v. I've read for solar systems exceeding ~600w, one should consider going to 24v - if no DC load exceeds ~30amps. The reason for this apparently is because most step down converters can't handle more than 40 amps or so. But since many towable RV's have hydraulic leveling systems that draw more than 40amps, it seems nobody could take advantage of a 24v system. What am I missing?
2- 12v vs 24v solar panels. It sounds like if I go with a 12v system I should use 12v panels. But, I've only found ONE manufacturer (Victron) that shows the panel voltage (12v vs 24v). Every other manufacturer I've looked into lists two dozen specs for their panels but not one of them identifies them as 12v or 24v. Clearly I'm missing something. This information must be buried in all the other specs that are listed. Does anybody know how to identify whether a panel is 12v or 24v?
3- Inverter vs inverter/charger. The vast majority of people that build solar systems seem to get a combination inverter/charger. Do these people disconnect their factory converter/chargers? Are they getting combo units because they haven't yet replaced their OEM charger for a model that will charge LiFePO4? Can you leave the OEM charger/converter in place and use a combo inverter/charger at the same time?
