SMH Specifications 1

• Currently, Voltronics inverters can only speak to a small number of lithium batteries. With SMH we can add any battery with a communications interface, ensuring that the Voltronics brand is used in more installations worldwide. We firmly believe that this feature alone will drastically increase the sale of Voltronic inverters across the globe.
• SMH can also be white–labelled / OEM, so it can become branded for every customer that has an OEM agreement with Voltronics.
• SMH can also do the switching between utility and battery mode based on the true SOC of the batteries (not voltage), because we can talk directly to the BMS, which in turn gives much more value to the end user as they will get proper runtimes out of the lithium batteries they bought.
• Using SMH there will be no more false positive warranty claims, as we log every change on the inverter, together with who did it (the installer or the end user), so it’s very easy to spot wrong configuration settings or anything else that lead to inverters and/or batteries failing.
• With support for the Victron BMV range of battery monitors, SMH can also provide true SOC reading and switching of lead–acid batteries, making it the perfect companion for older systems that still use those batteries.
• SMH support native Telegram message sending when anything goes wrong in the entire system, with configurable inverter errors to be sent, together with things like low battery alarms, utility failure or restoration, hardware disconnect errors, etc. No external modem required. Email alerting is also part of the package
• SMH has a native IOS and Android app for live monitoring of the system and also to control the inverter by applying profiles.
• SMH support almost all the Voltronic inverters, including the Axpert and Infinisolar range.
• SMH is extremely lightweight and runs on a cheap raspberry[p pi computer, negating the need for a spare laptop/desktop machine that has to run 24/7 to read the inverter data.
