Stationary batteries used for solar power are different from stationary batteries used in UPS or other applications though both are made using tubular positive plates and thick pasted negative plates. A battery made for solar application is rated at 120 hr rate for a discharge at very low current over a long duration.

You can directly connect solar panels to the solar UPS. Utility power is not the only power source. The UPS will utilize solar power to charge the battery when the grid is not available. With SBU priority smart management you can prioritize UPS’s energy source based on your preferences.
