I understand solar inputs into Bluetti units may be limited to 12A current for some units (like EP and some AC models - also portable units may have lower current range). But because the voltage range is sometimes more flexible (35-150V/Max.12A for each MPPT on EP500P). It would be ideal if Bluetti produced a device to step up voltage (DC-DC boost converter) configurable for various series of Bluetti devices to allow optimal solar input. Setting up solar panels in series may not be ideal for some users due to shading or placement restrictions in order to achieve higher voltages, so solar panel configuration is currently somewhat limited for such users.
Additionally, such device could even feature more MPTT controllers than available to current EP/AC or portable units and allow users to optimize DC input for a given Bluetti model. Such add-on Bluetti MPPT/boost converter would allow/encourage existing Bluetti customers to purchase much more solar panels and optimize solar power into current units. Additionally, it could promote the use of additional Bluetti solar generators because solar production could be optimized much easier.
Currently there are not much products in the market that could be used to achieve this or with any level of efficiency to work well with Bluetti solar generators.
