Soluna系统是一种新的能源解决方案，内部集成能源管理系统功能，可以控制和优化能源流量，从而最大限度地提高光伏发电的自用率。光伏产生的电能优先考虑供应负载，当PV能量过剩时，可以对电池充电以存储能量，这样就可以在没有光时使用。如果光伏还有多余的能量将会反馈到电网中，当电网出现故障时，Soluna可以切换到应急备用模式并继续向负载供电。

Verdict
The clearest difference is update cadence: Soluna at every 2 months against RPEMS's every 10 months. Soluna also leads on iOS requirement (8.0 vs 12.0). On price, ads, in-app purchases and device support there is nothing between them.
