Which plan is more suitable for you? Let's recommend a set of configurations (12V/3000W system):1. 3000W high frequency sine wave inverter with bypass function.
Advantages: When the main supply is connected, the electricity in the RV will be directly transferred to the mains supply, the inverter will no longer work, and there will be no self-loss and heat generation. Usually not connected to the mains, the high-frequency sine wave inverter has the advantages of high conversion efficiency, low self-loss, and low heat generation. The actual 6000W peak power of 3000W inverter can start most of the large electrical appliances in the RV, overhead air conditioners, household air conditioners, kettles, audio-visual systems, etc.2. MPPT solar controller 12V/24V/48V adaptive 60A.
Advantages: Why choose 12V/24V/48V adaptively? The reason is that in case you change the 48V system on a whim, you can still use it. The 48V/60A MPPT solar controller can support up to 876W (14.6V*60A) solar panels, but in fact, even if we install 800W solar panels on the RV, under normal circumstances, it cannot reach such a large power. But if your configuration is too small, you will not be able to achieve the maximum effect. The 60A MPPT solar controller can meet most of the DC load, even if the weather is not so good, the electricity generated is enough for the DC refrigerator.3. 12.8V LiFePO4 dedicated mains charger 100A.
Advantages: When connected to the mains, quickly charge the life battery in the RV. We mentioned this charge and discharge coefficient when we talked about the battery above. If the lithium battery is 200AH and the charge factor is greater than 0.5C, it only takes 2 hours to fully charge the battery when it is connected to the mains. The advantage of the independent AC charger is that it has its own fan and over-temperature protection function, which is more stable and safer in the state of mains charging.4. 12V to 12V dual battery isolator 120A.
Advantages: I personally think that this will be the best and fastest charging method. If our car generator has a charging current of 100A, when this dual battery isolator is installed, it can charge 1.2kWh every 1 hour when driving. For RV users, it is the most comfortable state to drive for 3 hours per trip and rest for one night at the station. If equipped with dual battery isolators, it can fully meet the electricity needs of one night. So please don't ignore this key configuration.
