Growatt SPF 3000-5000TL HVM Off-Grid Inverter
This off grid inverter is suitable for a maximum circuit voltage of 102VDC. The inverter can be used with batteries, but can also work without. The integrated solar charger optimizes the charging and discharging of the battery. Priorities can be assigned, where for example charging from the grid can be preferred over charging from the PV installation. Monitoring will be possible when adding a separate Wi-Fi or GPRS dongle. This off-grid inverter can be used in parallel with a total of 6 inverters.
The solar charger helps to maximize the longevity of the battery. This is partially because the solar charger continuously regulates the charge from and to the battery. The battery will, because of it, be protected from either being overcharged or fully emptied.
A separate dongle allows to connect the inverter with for example a mobile phone or desktop computer. This lets you connect and check the status of the entire PV system. The dongle has a Wi-Fi and GPRS version.
