Telecom Tower Bank Round-Trip Efficiency
Measure AC round-trip efficiency of a telecom tower bank and price the annual energy lost.
Every cycle of a telecom tower bank eats a slice of energy — inverter losses both ways, BMS standby, cell resistance. Tower sites with unreliable grid cycle their banks daily in soak-and-discharge patterns; the lead-to-LFP refresh wave is driven by diesel-generator savings per site. Meter a full charge and a full discharge at the AC side and this tool reports true round-trip efficiency, flags it against the chemistry's expected figure, and prices a year of losses at your tariff.
Measure both directions at the AC meter so inverter losses are included. A falling RTE trend usually means rising internal resistance (aging) or an auxiliary load (HVAC, BMS standby) leaking into the count.
Engineering estimate from published standards and typical equipment data. Site conditions, equipment datasheets and measured data govern the real result — confirm with a qualified engineer.

Frequently asked questions
What round-trip efficiency should a battery system achieve?+
AC-to-AC including the inverter: LFP/NMC systems 88–94%, lead-acid 75–85%, vanadium flow 70–80%. The DC-only figures vendors quote run 3–6 points higher — always compare at the AC meter, where you're billed.
Where do battery losses actually go?+
Inverter conversion (2–4% each way), cell internal resistance (heat, rising with age and current), and auxiliary loads — BMS standby, cooling fans, heaters. In small systems, standby drain across idle hours can quietly halve the apparent efficiency.
My measured RTE is far below spec — what should I check?+
First the measurement window (include only charge-discharge, not idle days of standby drain), then auxiliary loads on the battery side of the meter, then cell aging (rising internal resistance). A 10-point RTE fall with age is a legitimate degradation signal worth a capacity test.
Does round-trip efficiency matter for solar self-consumption?+
Directly: every stored kWh costs you 1/RTE kWh of solar. At 90% RTE the toll is mild; at 75% (old lead-acid), a quarter of your stored solar evaporates. The annual-cost line in the Telecom Tower Bank Round-Trip Efficiency prices this for your cycling pattern.
