Specifications
Product Description
The MPPT Controller TBB Power SP250-70 250 V 70 A 24/48 V offers higher input voltage and charging current for systems that require longer cables and higher power PV arrays. With a tracking range of 65–245 V, it supports up to 2.7 kW (24 V) or 5.4 kW (48 V) of photovoltaic power, maintaining a 365-day data log, RS485 communication, and TBB II algorithm for lead-acid and lithium batteries.
Main Features
- 70 A charging for 24/48 V battery banks.
- PV input up to 250 V Voc; MPPT range 65–245 V.
- Admissible PV power: 2.7 kW (24 V) / 5.4 kW (48 V).
- Efficiency up to 98 % and MPPT efficiency ≥ 99.9 %.
- Forced ventilation for continuous operation and longer service life.
- LED+LCD display, RS485, dry contact, and 365-day datalogger.
Advantages or Benefits
- Longer cabling and reduced losses thanks to the 250 V PV bus.
- Fast battery charging due to its high 70 A current.
- Protection and care for AGM/GEL/open lead-acid and LiFePO₄ with dedicated profiles.
- Precise tracking that maintains production even with partial shading and thermal changes.
Purpose or Applications
Off-grid and medium/high power self-consumption at 24/48 V: homes, businesses, telecom, technical cabins, and backup systems where high PV voltage and 70 A charging are required.
